CUSTOM COMPONENT EDITING 14 End Plate Connection

2 End Plate Connection

2.1 Define Custom Connection 8. Create two IPE300 beams as shown and an end plate (144) to connect them.


9. Explode the connection.

10. Define a custom component connection by following the instructions in the wizard.

Parameters to be used In this example we will input the following parameters:

Once all parameters have been defined the finished result should look something like in below:

Additional information: Plate length 7 = Plate width 6 = Plate thickness Plate material Bolt size Bolt grade

1 = Clearance from flange face 2 = Notch depth 3 = Distance to 1st bolt 4 = Bolt pitch 5 = Bolt C/Ctrs


The connection should also have the intelligence to adjust a change in the profile of either the main or the secondary beam.

2.2 Create magnetic planes to control Top Notch

We are going to define the notch first. The values we would like to input are:

As for the clearance from the flange and the depth from the secondary beam top, we are going to use magnetic user planes to control these variables.

Select the connection symbol, right-click and select: Edit custom component.

1. From the Custom component editor toolbar double click Create construction plane.

Open the custom component editor

Create User defined planes


2. Add a tick to the magnetic box and OK.

5. Repeat creating a vertical plane by picking the corner points as shown


6. Copy the planes to the opposite faces of the cut

2.3 Adjust the planes for different notch sizes In case we want to enlarge the existing notch it results easily the notch chamfers to be outside the magnetic planes. In order to cover also larger notches we need to adjust the magnetic planes

Only the objects directly on the magnetic plane move with the plane.

Note that the objects must be inside the plane frames to move with the plane

We will now move the handles in the plane corners to enlarge the planes to cover all the polygon cut sizes possible needed (the fig below)

Select both the horizontal planes and then their handles on the secondary beam side

Move the handles 100 mm to the direction shown


Repeat to move vertical planes lower handles 100 mm downwords

We can now bind the planes to define the input dimensions.

7. Select the horizontal user planes one by one and bind them to the top of the main beam.

8. Bind the vertical plane highlighted in the fig. below to the flange edge of the main beam.

Bind the planes


9. Bind the other vertical plane to the web face of the main beam.

2. Make these variables to follow the plate thickness by adding the plate thickness as an equation to the variables.

3. Set the visibility of variables to Hide.

Tie the plate to the main beam


2.8 Add Intelligence to the Bolts

1. Double-click on the bolt group and set the start and end offsets to zero, Modify.

2. Bind the upper handle of the bolt group to the top of the secondary flange. A new

variable D9 will appear.

Distance from top flange to 1st bolt


3. Add a new variable, name it as Top flange to 1st bolt and edit the value to 70.

4. Edit the formula of variable D9 to be = -P6

1. Add two new variables.

2. Change the value type of the first variable to Bolt size and the second to Bolt standard.

3. Select the Magnetic check box, change the Extension to 100 and click OK.

4. Create six construction lines to the middle edges of the plates as shown to control the

size of stiffeners (Pick two points to define the location of the line)

You can also use user defined planes (Magnetic or not) to bind distances to make it easier to pick the stiffeners corners hide the main part.


5. Create one magnetic plane in the middle of the plates to control the plate's position in depth.

INFO: This magnetic plane will control also the position of the construction lines (handles)

The objects must be inside the magnetic plane frames to move with the plane. To make this detail work for significantly larger profiles we should enlarge the planes.

3.3 Bind construction Lines to the Beam

1. Tie the magnetic planes to the appropriate faces of the beam.

12 new parameters appear in the Variables dialog box.

Tie magnetic planes to beam


2. Set the visibility of the variables to Hide.

The distance variable visibility in the variables list is by default Hide if the distance equals to zero. Otherwise it is Show.

3. Tie the magnetic plane in the middle of the stiffener to the connection plane shown.


4. Name the variable as Position at depth and set it to show.

5. Close the editor and save the custom component.

1. Change the beam profile from HEA300 to HEA200.

The height and width of the stiffeners are now adjusted to the new beam profile whereas the thickness of the stiffeners is always the same.

2. Change the beam profile back to HEA300.

Test the custom detail


3.4 Use Equations to Make the Plate Thickness Intelligent

We will now adjust the stiffeners' thickness to suit the web thickness of the beam so that it will be 1.5*beam web thickness rounded up to the next available plate thickness. The available plate thicknesses are 10, 12 and 16 mm.

We will first add a new variable that returns the beam web thickness multiplied by 1.5.

1. Open the custom component editor.

2. Add a new parameter and change its Value type to length.

3. Add the equation =1.5* to the variable.

4. Select the beam in the model.

5. Select Primary part > Profile properties > Web thickness in the model browser, right-click and select Copy reference.

6. Paste the reference to the Formula after 1.5*

A reference function refers to the property of an object, such as the web thickness of a part. If the object property changes, so does the reference function value.

1.5 * Web thickness


We will now use an if-then-else statement to test whether the variable P1 is bigger than the condition and set the value according to the result.

1. Add a new variable and change its value type to Number.

2. Edit the Formula of the variable P2 to be =if (P1 < 12 && P1 > 10) then 12 else if (P1 > 12) then 16 else 10 endif endif

Define the condition for the plate thickness


Tie the parameter P2 to plate Profiles in the model browser.

CUSTOM COMPONENT EDITING 54 Add a User Interface to Ladders Custom Part

5 Add a User Interface to Ladders Custom Part

We can make our Custom components easier to use by customizing their dialog boxes. By modifying the input file of the custom component we can:

• add pictures

• change the order and location of fields

• add / rename tab pages.

We will next add a picture to the ladder simple custom part. We will then position the parameters and group them to two different tab pages: Picture and Parts.

5.1 Create and Save the Picture We will first create the image and save it as a bitmap file. We will then add the image to the custom component dialog box by editing the custom component's input file.


1. Take a snapshot of the shown region of Ladder macro (S35) dialog box.

2. Edit the picture to be as shown below using any picture editing program. (The size of the example picture is 62*250 pixels.)

To create the picture you can open an existing bmp from the teklastructures\”version”\nt\bitmaps directory or take a snapshot from an existing component dialog box and edit it by using any picture editing program. You can also create the bmp from the scratch.

Remember to use the standard Tekla colors in the bitmaps.

Create the bmp


The first pixel in the top left corner of a bitmap must be the same color (grey) as the background of the dialog box.

Save the completed picture to the teklastructures\”version”\nt\bitmaps with the name ladder.bmp.

5.2 Add the Bitmap to the Dialog Box Tekla Structures uses input files to control dialog boxes.

A custom component dialog box is controlled by an INP file automatically generated in the model directory. We will now edit the Ladder simple.inp file to customize the dialog box of our custom part.

1. Open the Ladder simple.inp file in the model folder using a normal text editor (Notepad, WordPad...)

2. Add the text: picture ("ladder", 62, 250, 100, 50) to the inp file as shown below.

Place the bmp file in the system folder

Edit the inp file


3. Save the inp file (In txt format).

4. Close and restart the model to see the modified dialog box.

5. Study the dialog box to understand the positioning of the picture.


5.3 Position the Picture and the Parameters We can now plan the picture page and position the parameters P1-P6 according to the ladder picture as shown. We will position parameters P7 and P8 at this stage at the bottom of the dialog box.

1. Remove the parameter names from parameters P1-P6.

2. Add the X, Y coordinates and the length of the field for parameters P1-P6.

The number of fields and the coordinates added will effect the size of the dialog box. Each tab page can contain 25 fields. If there are more than 25 visible fields, Tekla Structures creates another tab page.

Position the picture and the parameters


3. Change the order number of parameters P7 to 15 and P8 to 16.

4. Save the inp file.

Reopen the model to check the dialog box.

Reopen the model


5.4 Add and Rename Tab Pages We will now rename the parameters 1 tab page to Picture and then add a new tab page Parts to the dialog box. Then we move the profile parameters to this new tab.

Replace the text Parameters 1 with Picture.

1. To add a second tab Parts, edit the input file as shown below.

2. Save the file.

Rename a tab page

5. Interrupt the command. 6. Select the start point of the insulation and bind it to the same plane. 7. Repeat for outer panel's start point. 8. Repeat for the end points of all three panels. The distances appear in the Variables dialog.

9. Close the editor and save the component.

6.2 Test the Bindings by Creating a New Sandwich Panel

1. Select the Sandwich_Panel in the component catalog.

2. Pick start point. 3. Pick end point.


All panels of the Sandwich should start and end at the component's definition points.

6.3 Parameterize the Panel Thicknesses Panel locations must follow the thickness changes. Therefore we must set controls for the definition points. First bind the inner panels' definition points to the component plane. 1. Set the plane to Component planes in the Custom component editor toolbar.

2. Select the start point of the inner panel. 3. Bind it to the component plane which is parallel to the panel's long side.

4. Repeat for the end point. Next bind the insulation panel's definition points to the inner panel's outer side. 1. Select Boundary planes in the Custom component toolbar.


2. Modify the inner panel's height so, that it can be picked from the outer side. 3. Select the start point of the insulation panel. 4. Right-click > Bind to plane. 5. Pick the outer plane of the inner panel.

6. Interrupt the command. 7. Repeat for insulation panel's end point. Now the insulation panel follows if the inner panel's thickness changes. Next bind the outer panel's definition points to the outer side of the insulation panel. 1. Modify the outer panel's height so, that the insulation panel can be picked from outer

side. 2. Select the start point of the outer panel and bind it to the outer plane of the insulation

panel. 3. Repeat for the end points of outer panel. The outer panel now follows the insulation panel. The distances appear in the Variables dialog. Hide all parameters by setting the visibility to Hide.

Define next the panel thicknesses to the Variables dialog. 1. In the Variables dialog press the Add… button. 2. Change the Value type to Profile. 3. Give a label Outer panel. 4. In the Custom component browser open the outer panel's Part > General properties and

right-click > Copy value over the Profile field.


5. Paste the profile value into the corresponding Formula field in the Variable dialog 6. Repeat for the insulation and inner panel.

We have now defined parameters for all profiles. Next we will map these parameters into the custom component parts. 1. In the Custom component browser open the outer panel's Part > General properties

and right-click > Add equation over the Profile field. 2. Type the parameter's name into the field.

3. Repeat for insulation and the inner panel. Next separate the thickness and height into two individual parameters for each panel. 1. In the Variables dialog press the Add… button 6 times. 2. Write the labels as shown below:

3. Copy the corresponding values from the profile parameters into the "Formula" field

4. In the profile parameters write new formulas using the parameters:

5. Hide the profile parameters and leave the individual dimensions visible. 6. Set =P5 into the D9 and D10 formula fields to make the dimension react to thickness. 7. Set =P6 into the D7 and D8 formula fields to make the dimension react to thickness. 8. Close the editor and save the component.


In the model, double-click the sandwich panel and modify the thickness and height values.

CUSTOM COMPONENT EDITING 71 Create a Reinforcement Seam

7 Create a Reinforcement Seam

We will next create hooped reinforcement bars and seam bars at the end of the hollow core slabs using the seam type custom component.

7.1 Insert the Members For the seam type custom component we need concrete members – a beam and hollow-core slabs – and reinforcements.

Concrete members 1. Create a beam with the profile 780*380 at Middle on plane and Behind at depth

position.

2. Add 10 hollow core slabs P27(265X1200) at Right on plane and Front +10.00 at depth position.


Reinforcements 1. Create dowel reinforcement bars to the beam using the values below. Create Part basic

views of the beam to help modeling.

2. After applying the dialog values, pick the beam.

3. Pick a reference point at the middle of the beam top in the Part end view using Ctrl + pick.

4. Point the up direction with the cursor (do not pick) and enter 200 numerically and click OK.


5. Point the down direction with the cursor (do not pick), enter 800 numerically and click

OK.

6. Press the middle mouse button.

7. Point the beam start point.

8. Point the beam end point – a reinforcement bar group is created.

Next create the reinforcements at the hollow core slab seams.

1. Enter the values as described below to the Reinforcing bar properties dialog (the values in the Group tab page is same as in previous one) and close the dialog with OK.


2. Pick the beam.

3. Pick a reference point at the middle of the beam top in the Part end view using Ctrl + pick.

4. Point to the beam inner top corner (do not pick) and enter numerically 1400.

5. Point to the same point again (do not pick) and enter numerically 1500.

6. Enter numerically 0,0,250.



9. Point the beam end point – a reinforcement bar group is created.


10. Select the reinforcement and right-click > Detach from part. Now the group does not

belong to any cast unit.

Finally create the hooped reinforcement bars.

1. Enter the values as described below to the Reinforcing bar properties dialog and close the dialog with OK.

2. Pick the beam.


4. Point the beam end point.



6. Point the start of the group at the middle top of the beam (1).

7. Point the end of the group at the hollow core slab top corner (2). A reinforcement group is created. Select the reinforcement and right-click > Detach from part.

7.2 Define the Seam Custom Component When the members have been modeled we can create the custom component.

1. Open the Custom component wizard with Detailing > Define custom component.

2. Select Seam as the component type.

3. Enter the name "Hooped_rebars".

4. Write description: "1) Pick the beam, 2) Pick the first hollow core slab, 3) Press middle button, 4) Pick start point for seam, 5) Pick end point for seam"

5. Click Next>

6. Select the three reinforcement groups.

7. Click Next>

8. Pick the beam as the main part.

9. Click Next>

10. Pick the first hollow core slab as the secondary part.

11. Click Next>



12. Point the beam end point.

13. Press the Finish button – a custom component is created.

7.3 Parameterize the Seam The rebar group definition points must be bound to the component start and end points so, that they define the length of the seam. We also add controls for the reinforcement parameters on the dialog.

1. Select the component symbol and right-click > Edit custom component.

2. Bind, first, the dowel group's definition points to the component planes. Make sure that you have Component planes selected in the Custom component editor toolbar. Select the group start point.

3. Right-click > Bind to plane.

4. Pick the end plane at the same end of the beam where the selected point is.

5. End the command and select the end point of the same group.


7. Pick the end plane at the same end of the beam where the selected point is. Repeat for the third direction.

8. End the command and repeat the steps for the seam and hooped reinforcement groups. For the hooped group, select the form definition points.

Next, we will add controls for the reinforcements to be shown on the dialog. First, we will change the plane from Component planes to Boundary planes in the Custom component editor toolbar.

1. Select the dowel group's up-most form definition point.


3. Pick the beam's top plane. A distance is created.


4. Select the lower form definition point and bind it to the same plane.

5. Select the seam reinforcement group's up-most form definition point and bind it to the same plane.

6. Bind the form definition points of the same rebar group to the end plane of the hollow core slab.

The distances appear in the Variables dialog. Change the Labels for visible parameters as shown below:

1. Close the editor and save the changes. The reinforcements can now be edited from the dialog.


Appendix C: FAQ

Q1. Are there any reserved parameter names? A1.Yes for “bolt size” the parameter name needs to be “diameter”, & for “bolt standard” the name needs to be “screwdin”. Bolt size & bolt standard MUST have the same name. The names are automatically given when changing the “Value Type” so the bolt standard variable name will have to be changed to suit the bolt size variable name

If they do not have the same name the result will be as follows:

No value show in the “bolt size” dialog

Q2. Is there any way to know what is bound to what? A2. Use inquire This will show all binding dimensions

Q3. How to bind to a user defined plane?


A3. You can bind to user planes by simply selecting them. Note! They will not be highlighted.

Q4. Are there any “best methods” to creating custom components? A4. Not really, although multiplication is faster than division. E.g. P1*0.5 is faster than P1/2. Also using magnetic planes is faster than binding all handles

Q5. How to add pictures to “inp” file? A5. See the online help for detailed instructions Q6. If a picture is added to the inp file then changes are made in the editor is the inp file overwritten A6. Yes, you need to make a copy of the modified inp file Q7. When editing the “Inp” file I can’t use “Tab 4” A7. This tab is reserved for the General Tab

Q8. I want to input 2 separate values for the plate width and thickness how can I use these values to make a “profile” name e.g. PLT200*10? And how to stop the values being input with decimal places A8. If as in the example below you use P2 for the plate width & P3 for the thickness use the formula “=”PLT”+int(P2)+”*”+int(P3)”. All text must be in inverted commas “”, int() will stop the values being input with extra decimal places.

Q9. Is it possible to change an existing binding? A9. No, you must delete it and re bind


Q10. Is it possible to rationalize a value to the nearest (for example) 10? A10. Yes, Use function round(), in this case round(P1, 10). Some other examples: round(17.5, 20) will round 17.5 to 20 and round(17.1, 5) will round 17.1 to 15.

Q11. Can you use formulas in a distance list? A11. Yes, this is possible. Below is an example of using formula in distance list.

Distance list is treated as text in Tekla Structures, so formula should be written as e.g. P1 + " " + P2 or "2*"+P2.

Q12. Is there any way of changing the variable name for parameters created by binding to a plane? (AB) A12. No, these are system defined names and will cause problems if the user is allowed to change the name (TIP: If you try to change the name it will allow you to change it but when you reopen the variable table is will have changed back)

Q13. Is there a limit to the length of the variable label? A13. Yes 30 characters, but you can add more in the inp file

Q14. What does the “create distance” command do on the “custom component editor toolbar?”


A14. With this command you select the plane first then the handle/chamfer to bind. It’s the opposite of “right click /bind to plane”

Q15. What does “create distance for picked components handle points” command do on the “custom component editor toolbar?” A15. This is a command to automatically bind selected parts to their handles contact planes. (User planes 1st, then part planes of main & secondary member)

Q16. Why isn’t the browser tree updated when I add or delete parts in the custom component editor A16. You need to refresh the tree by right clicking on the connection part of the browser

Q17. Can we change the standard properties of the custom component editor views? A17. You can change the properties but you cannot save them. Q18. Can we bind to the centre of profiles?


A18. Yes using boundary Planes, It may be necessary to rotate the view until you can select the center plane.

Boundary planes

Q19. Is there any difference between outline and boundary planes? A19. Yes “outline planes” follow the outline of the member and “boundary planes” form the outer shape of the member. TIP: Where possible it is better to use the boundary planes rather than outline planes as these are common between different shapes. Q20. Can we filter out the magnetic/user planes? A20. No not using filter or display but you can hide them using the new hide option, (user planes use the point section filter)
