Enhancements in sp5


Whats New in Orion 18.0 sp5 May 2014 Please note that service pack 4 was not put on general release.

Enhancements in sp5 Axis Table Editing

In the Axis Table label balloons can now be modified column-wise.

Fixes in sp5 The following errors have been corrected:

Punching Shear Check Dialog for an Individual Column In release sp3, the punching shear dialog for checking an individual column was not working correctly. The buttons for selecting the column location had stopped working so that you could only check the column using the centrally located option.

Different concrete grades for walls and columns Although you were able to define different concrete grades for columns and walls, in the analysis model the walls and columns were assigned the same material property - i.e. the concrete grade assigned to the columns. The grade assigned to the walls was ignored in analysis. Member design was unaffected: the columns were designed for the concrete grade assigned to the columns, the walls were designed for the concrete grade assigned to the walls.

Hogging moment in a beam connected to a column via a rigid beam When a beam connects to the centre of a column, a rigid beam is used to model that portion of the beam that exists within the column perimeter. The properties assigned to the rigid beam are much stiffer than those of the beam itself.

An error could occur if a second beam framed in to the rigid beam that exists at the start of the first beam: in this situation the torsion constant assigned to the rigid beam was wrongly reset to that of the first beam.

Fixes in sp5


This caused a reduction in the hogging moment at the end of the second beam and an increase in its span moment.

Expected bending moment diagram in the second beam.

Actual bending moment diagram in the second beam.

The potential for the reinforcement at the end of the second beam to be under-designed was however limited because it was also designed for a percentage of its span moment. In sp5 the torsion constant for the rigid beam in this situation is no longer being reduced.

Beam Design to EC2 In BS EN 1992-1-1:2004 clause 9.2.1.2, the minimum design moment at the support is determined by applying a 1 factor to the span moment, where: 1 = the appropriate NDP partial fixity coefficient For design in accordance with the UK NA, Irish NA, Malaysian NA or Singapore NA; 1 = 0.25 For design in accordance with EC2 Recommendations; 1 = 0.15 Previously the program was incorrectly taking 1 = 0.15 when designing to the Irish NA, Malaysian NA or Singapore NA. It now correctly uses 1 = 0.25 in these cases.

Column Section Area For all EC2 National Annexes apart from the UK: creation of a small column (e.g. 270mm x 270mm or less), resulted in an incorrect warning "column section area less than min area requirement (0.075m2)" being displayed on screen. The warning could be ignored and there were no design consequences. This incorrect warning has now been removed.

Beam Design Dialog In interactive beam design, when you viewed a beam's steel calculations and closed the calculation dialog, the Reinforcement Data tab was selected automatically. In sp4 the dialog has reverted to selecting the Axis and Beam Data tab.

5

Fixes in sp5


Beam Detail Drawing Arrangement

On the Detail Drawing Arrangement dialog for beams there is a checkbox to Display Every Sheet Prepared. This checkbox was not functioning. In sp5 it is now working correctly.

Column Detail Drawing Arrangement

On the Detail Drawing Arrangement dialog for columns there is a field to set the Number of Columns in the Sheet. The maximum number that could be entered in this field was 9, so that it was not possible to display more than 9 columns in a row across the drawing sheet. This restriction has been removed.

Beam Table Editing In sp3 column-wise editing of beam dimensions was not functioning correctly.

Stability Issues A number of stability issues with non-critical design consequences have also been addressed.

6

Previous Enhancements


Previous Enhancements Beam detailing (sp3) On the detail drawings, extension and lap dimensions are now rounded to the total bar length rounding step, whereas in previous releases they were being rounded to the nearest 5mm. To illustrate the effect of this change, consider the example below: Typical 18.0sp3 detail (in which the bar length rounding step has been set to 50mm)

The same detail produced in 18.0sp1 for comparison

This enhancement has been made in response to user feedback so that drawings do not have to be manually edited in order to indicate more rounded lapping and anchorage lengths. Although the extension and lap dimensions are now displayed differently on the drawings, the total bar length reported in the schedule is unchanged from previous releases.

Adjusted shear area properties in FE column head model (sp3) When the option to include column sections is applied, the rigid members used to model the column head were previously assigned a shear area equal to 5/6 of the column area. Consequently some degree of shear deformation was possible across the column head. To prevent this, in 18.0sp3 a value of shear area is explicitly assigned which in general eliminates such shear deformations.

Editing beam level data in data tables (sp3) The functionality for editing the beam level data for multiple beams via data tables has been improved to cater for the input of negative values of h-top.

Highlights

2013 Version 18 May Delivered by

Whats New in Orion 18.0 May 2013 Highlights Orion 18.0sp1 contains several completely new features and a significant number of enhancements:

Beams now designed for torsion New polyline column editor Batch FE beam load decomposition New column centreline modelling in Building Analysis Enhanced automatic cantilever marking New column perimeter modelling in FE raft foundation analysis Plus numerous other enhancements.

Beam Design for Torsion This is a significant new feature which has been implemented for all the available design codes.

Torsion design to BS8110, CP65 (Singapore) and HK-2004 (Hong Kong) These three codes of practice share an almost identical method for the design of beams subjected to torsion. For each there is a limiting value of shear stress due to the applied torque below which the effects of torsion can be ignored. When the torque exceeds the limit the effects torsion are considered and if required torsion links are now provided.

The new torsion calculations for the above codes are included in the beam design report as shown below:

The extra terms for torsion design being:

Td = maximum torsional moment

vt = torsional shear stress

vt-min = minimum torsional shear stress, below which the effects of torsion can be ignored

As-T = area of longitudinal torsion reinforcement required

8

Beam Design for Torsion


Torsion design to Eurocode 2 The procedure to EC2 for determining whether or not torsional effects need to be considered is more complex. Minimum shear reinforcement can only be provided if the combination of the ratio of direct shear stress/shear resistance of the concrete without shear reinforcement plus the ratio of shear stress due to torsion/torsional cracking stress is less than 1.0.

The new torsion calculations for the Eurocode 2 are included in the beam design report as shown below:

The extra terms for torsion design being:

Td = maximum torsional moment

T-min = ignorable limit for torsional moment

t-RdC = torsional cracking stress

Str.Ratio = combined stress ratio - if less than 1.0 then only min. shear reinforcement needs to be provided.

As-T = area of longitudinal torsion reinforcement required

Torsion Detailing

In the above detail you can see that, to meet torsion design requirements:

side bars have added

the outer link is a single closed torsion link

torsion links are indicated on the elevation by inclusion of (T) in the bar mark

NEW Polyline Column Editor


NEW Polyline Column Editor This is a major enhancement which now provides a means to define a reinforcement layout in not only polyline columns, but also rectangular/parallelogram columns prior to a check or design.

When checked - the specified layout and bar sizes are both fixed.

When designed - the specified layout is fixed, but the bar sizes are incremented to achieve a solution.

The main benefits of using the new Polyline Column Editor are:

It is no longer necessary to perform an initial design in order to access a first pass steel layout, (which can often turn out to be unsuitable, needing to be reviewed and amended interactively).

Using the new editor, bars can rapidly be positioned, either automatically or manually.

It can be used to specify the layout in rectangular or parallelogram columns as well as polyline columns.

The Polyline Column Editor Interface The existing commands for defining the column perimeter have all been retained and are located on the Edit Section toolbar. Extra commands for positioning the steel bars can be found on the new Steel Layout toolbar.

10

NEW Polyline Column Editor


Overview of the Steel Layout toolbar

The buttons on this toolbar enable you to set up a practical steel layout efficiently in advance of a check or design.

Button Command Function Notes

Automatic Containment Automatically positions longitudinal bars and links within the section.

Displayed for rectangular/ parallelogram columns only.

All Links Automatically positions links within the section.

Displayed for non-rectangular columns only.

All Bars Once links have been defined, this button automatically

positions longitudinal bars within the links. Displayed for non-rectangular columns only.

Move Origin This button can be used to move the origin position. The origin defines the section

location in relation to the insertion axes

Delete Steel Bars

Deletes all existing longitudinal bars shown within the section.

Delete Steel Bars and links

Deletes all existing longitudinal bars and links shown within the section.

Corner Bar Used for manually placing corner bars within the section.

The polyline column editor cannot be used to define wall panels. The options shown on the left can only be used where components of a polyline column have a wall aspect ratio.

Web Steel Used for manually placing web steel within the section.

Mesh Steel Used for manually placing mesh steel within the section.

Closed Link Sets the default link to Closed

Straight Link Sets the default link to Straight

U Link Sets the default link to U Link

When a four sided column is passed into the Polyline Column Editor the Automatic Confinement button becomes available. When it is clicked, the dialog shown below is opened; this can then be used to specify both the layout and bar sizes for the selected column.

11

Batch FE Beam Load Decomposition


Batch FE Beam Load Decomposition FE Beam Load Decomposition can now be performed for the whole building in a single batch run, (previously it was necessary to select and then mesh every floor interactively). This will be of particular benefit where many floors have to be considered.

12

Column centreline modeling in building analysis


Column centreline modeling in building analysis For the building analysis model created in previous releases, the column analysis wire would be positioned at the axis intersection point; in release 18.0 it is now shifted to the true column centroid, with rigid links being created for beam connectivities, running from column centroid to the beam insertion point.

As a consequence the user is freer to simplify gridline layout in order to create the structure effectively, and then employ column eccentricities, (e1 and e2) to position each column exactly; knowing that during analysis the program automatically assumes the column is located at its centroid as shown in the plan view.

The example shown below is used to illustrate the change. The example model features a 1000mm wide transfer beam supporting a 500mm square column positioned flush with the outside face of the beam. Vertical load is applied to the transfer column from the beams above.

The model is created in release 17.0sp6 and then analysed - the results are then compared with those obtained in release 18.

Model creation and building analysis (in release 17.0sp6) The model is initially created with a simple grid layout.

The beam and its supporting columns are placed centrally on the grid, the transfer column is placed on the same grid with a column eccentricity (e2 = 250) to offset the column centroid.

In release 17.0sp6 (and other previous releases).

Having performed building analysis, the diagram to the right shows that there are no out of plane bending moments.

Because the column analysis wire gets positioned at the axis intersection point, the eccentricity of the beam end reactions at the top of the column is ignored as a consequence no moments are generated out of the plane of the frame.

13

Column centreline modeling in building analysis


In order for the eccentricity of the loading to be taken into account it is necessary to refine the original model. This is achieved by introducing a second parallel grid (A1) to offset the transfer column centroid. For the transfer column to be properly supported in this situation it is also necessary to split the transfer beam into two elements.

Having remodelled the frame as described, it can be reanalysed in release 17.0sp6.

As can be seen when the out of plane bending moments are reviewed, the eccentricity of the beam end reactions is now taken into account.

A rigid arm automatically connects each beam to the column centroid causing out of plane moments to be generated in the column.

Building Analysis in Release 18.0sp1 The original model with the simple grid layout can be re-analysed.

In release 18.0sp1

Because the analysis wire is always shifted to the true column centroid, the out of plane moments are generated without having to refine the original model.

Note: Although the analysis wire is shifted for analysis, in the post-processor view, as can be seen, it is still displayed at the original insertion point.

14

Automatic cantilever marking


Automatic cantilever marking This area has been significantly enhanced: Cantilevers are now automatically marked as you build the model.

Consequently during analysis it is much less likely that any cantilevers needing to be marked will be found but if any

are located the messaging at this point is improved to give a printable list, making it then easier to check which potential cantilevers need to be marked.

The operation of the Set Beam Support Conditions option you get when you right click on the beam group in the structure tree is changed previously it only deleted all cantilever marks now it will delete them and reset them to the automatic selections.

Bug Fix - The analysis setting option to switch off the checking of cantilevers (shown below) now works, it had stopped working in the previous release.

Enhancement/Adjustment where two potential cantilever beams meet at a point, only one is marked automatically;

however in previous releases, the one that was chosen was not always the most obvious. In response to user feedback the method of selection in this specific situation has been improved.

15

Column perimeter modelling in FE Raft Foundation Analysis


Column perimeter modelling in FE Raft Foundation Analysis The option to include column sections (which was previously only available at upper storeys) is now available at the raft level. This results in a better model which removes peak moments at column nodes consequently a more economical design can be produced.

Rigid members are added around the column boundary, which also connect to the column centroid, (in the same way as at upper storeys). Note that load from the column is always applied at its centroid rather than at its insertion point, (irrespective of whether column sections are included or not).

To illustrate this point, consider the two rafts shown below. Both are loaded at their exact centres by a single centrally positioned column. The only difference being that different insertion axes are used for each as follows:

Insertion axes for the left hand column are at the column centre (e1 = e2 = 500)

Insertion axes for the right hand column are at the top right corner of the column (e1 = e2 = 1000)

The two models produce identical results as shown below:

16

Other Enhancements


Other Enhancements FE Meshing

A number of previously logged meshing issues have been resolved in the release.

Slab Specific Subgrade Reactions in FE Raft Foundation Analysis In previous versions, if you specified a different subgrade coefficient for an individual slab in the slab properties dialog, it would always be taken into account when the FE model is generated.

In release 18 you now have added flexibility to perform the analysis if required using a uniform subgrade coefficient, without having to reset the individual values previously assigned to specific slabs.

When the above option is checked, the individual soil subgrade coefficients specified on each slabs property dialog are used so that you can cater for different soil conditions across the site.

When the above option is unchecked, the soil subgrade coefficient specified on the Floor Mesh and Analysis dialog is applied to all slabs, over-riding slab specific values.

17

Other Enhancements


Member Tables

Top level of slabs (Del-Z) has been added to the Slabs member table to facilitate editing. Also, column editing in member tables has been enhanced when a drop down is offered so the user is not restricted to the drop down values.

Model Export Options

An export option for SAP2000 R15 has been added for both the Building Analysis and FE Floor Analysis models.

Update Same Label Beam at other Floors This feature was previously introduced for columns only in release 17.0sp1 but has now been extended to work for beams also. It enables the copying of a beams section properties to the same label beam at other floors and is accessed via a new button on the Beam Properties, as shown below.

When the button is checked (as shown above) and the Update button is pressed, a dialog is displayed listing beams with the same label in other storeys.

This is a multi-select list; if you mark the other floors, cross-section properties are also updated in all the beams marked.

Generate Members to Other Storeys

During wall generation to other storeys, the beams in the target storey can now be deleted automatically (when the replace existing elements in target storey option is checked).

Beam Design and Detailing

A number of minor fixes/adjustments have been implemented in beam detailing.

18

Other Enhancements


In beam design the Ctrl key can now be used to select multiple rows to paste steel to in a single operation:

o Select the source row and click Copy Bars o Press Ctrl while selecting multiple destination rows o Click Paste Bars

The keyboard shortcuts Ctrl-C and Ctrl-V are now supported for copying and pasting steel bars. (R18 development work which we chose to release early in R17 sp5)

Beam Axis Editing was previously prevented for axes containing curved beams. Beam not included in any axis messages would be displayed incorrectly if you attempted to add/remove curved beams from axes. In response to user feedback the program has been enhanced to allow beam axis editing for axes containing curved beams.

(R18 development work which we chose to release early in R17 sp1)

Column/Wall Design and Detailing

A number of fixes/adjustments have been implemented in the wall detailing - many bar clashes have been addressed in the wall detailing and splicing of lateral bars added when length exceeds 12m.

In column/wall design the Ctrl key can now be used to select multiple rows to paste steel to in a single operation:

o Select the source row and click Copy Bars o Press Ctrl while selecting multiple destination rows o Click Paste Bars

The keyboard shortcuts Ctrl-C and Ctrl-V are now supported for copying and pasting steel bars. (R18 development work which we chose to release early in R17 sp5)

19

Other Enhancements


For column design the detail drawing settings now include a new Starter Bars Length Factor. The starter bar length will be calculated as a multiple of the bar diameter, or according to code requirements when the field is zero.


Templates

In the Ireland (Eurocode) template, the default load combination set is now based on a Max. G Factor of 1.35 instead of 1.25.

In all of the Eurocode templates, the default factors for slab steel extension lengths at interior and exterior supports have been standardised at 0.30xL and 0.2xL respectively.


Slab Design

The slab steel bob length which was previously fixed at 300mm is now user definable on the Steel Bars tab in Slab Design Settings.


Punching shear check

The general perimeter reduction length is no longer limited to a maximum of 999mm. (R18 development work which we chose to release early in R17 sp5)

20

Fixes in 18.0


Punching shear check at foundation level

This has now been enhanced to consider all load combinations and not just the (G+Q)*F combination. (R18 development work which we chose to release early in R17 sp5)

Refinement of Beam-Column Joint Check (Hong Kong)

Based on initial feedback the reinforcement overstrength factor is no longer fixed at 1.25; refer to the revised design procedure section 1.1 on page 363 of the Engineers Handbook.


Foundation Beams

At the foundation storey you can now insert multiple beams in one go by dragging between grid points under walls and columns. When a wall running in the same direction as the beams to be inserted is encountered, a Yes/No prompt is issued to ask whether these beams are for a strip footing insertion. If the answer is Yes then a beam is inserted from the start of the wall to the next support (which ensures the wall load is correctly handled in strip design). If the answer is No then a beam is inserted directly under the wall (and a warning is displayed if a strip is subsequently inserted).


Removal of FE Column nodal loads

When you use FE beam load decomposition in order to calculate slab loads, any isolated columns attached to the slab have FE nodal loads applied automatically. If you subsequently switch to yield line decomposition, in previous releases you would have been required to manually remove these loads. A new feature has been added which detects the FE nodal loads and gives you the option to remove them.


Column Labelling

On the Settings menu, the Member and Steel Bar Label Templates form contains a new option under Column Label Settings which allows you to control the location of the column size text in relation to the column label.


Fixes in 18.0 A number of stability issues and fixes with non-critical design consequences have been addressed.
