Run the STAAD Support Connection Wizard to Connect all orsome Supports to the Structure

First time the Support connection Wizard will start automatically

By Default all supports and anchors are selected but can filter by support type orunconnected or connected. In this example we will only connect Vstops and Guides.

In Piping Mode, Select Piping > Transfer Loads

This will define the mapping of AutoPIPE load cases to STAAD Primary or Reference loacases. By default class = Reference.

For Workflows transferring the Structure to AutoPIPE, it is recommended to set all pipinloads to reference loads and add them to the STAAD primary load cases as shown below

Defining Seismic Load Combinations

1) In STAAD.Pro

a. Define the structural model.

b. Import the AutoPIPE support reactions into a series of Reference Load case

say R1 to R4 for seismic , R5 for the gravity, R6 for pressure, R7 for therm

c. Define the UBC command along with the masses that need to be included,


19/43

which would include a reference to the pipe gravity load case:-

d. Define the UBC load cases that will be required, set the category of these

seismic (these must be the first load cases in the STAAD file, typically thes

would be:-

i. +X

ii. X

iii. +Z

iv. Z


20/43

e. Add the appropriate pipe seismic reference load case to the appropriate

primary UBC load case. E.g.

Primary

LoadcaseSTAAD Loading

AutoPIPE

Case

Pipe Reference

Case

STRUCT PIPE

AND STRUCT +XUBC X 1.0 E1 R1

STRUCT PIPE

AND STRUCT -XUBC X -1.0 E2 R2

STRUCT PIPE

AND STRUCT +ZUBC Z 1.0 E3 R3

STRUCT PIPE

AND STRUCT -ZUBC Z -1.0 E4 R4

f. Create the other required basic primary load cases dead, live wind etc.

g. Create the combinations using the Automatic load generator. As the pipe

reactions have been included in the same primary load case as the seismicloads from the structural UBC engine, there should only be 4 seismic

primary load cases defined. This would then create the necessary

combinations with each of the seismic primary load cases being considered

independently.


21/43

1) The Load combination generator should include a description for each rule which

used to provide a description to each combination that has been generated. A

default description could be Rule 1, Rule 2 etc would result in combinations:-a. Rule 1 (1)

b. Rule 1 (2)

c. Rule 2 (1)

d. Rule 2 (2)

e. Rule 2 (3) etc....


22/43

The user can specify a more useful description for their use. This would makepossible to see which rules have generated any specific combination. Also shthese in the Load Combination Generator:-

The current command shows the combination is generated from a specific codand table, but not which specific rule.

2) The UI showing the combinations lists the load cases as Load 1, Load 2 etc:-

Click Use Blank to export PIPELINK file same as STAAD filename

Note: It is not necessary but desirable to have the same PIPELINK filename exchanging between STAAD &

AutoPIPE. If click on the Use Blank button it will default to the STAAD filename. Otherwise browse to the

PIPELINK file imported from AutoPIPE and only new data like the Structure, restraints, releases, offsets and/

structural displacements will be updated to the PIPELINK file

In Piping Mode, Select Piping > Transfer Loads

This will define the mapping of AutoPIPE load cases to STAAD Primary or Reference loa

cases.

Note:Only displacement results for STAAD primary load cases can be exported toAutoPIPE.

One Recommendation for defining STAAD displacements to transfer to AutoPIPE is asfollows:


39/43

Define the Pipe Gravity load (e.g. R1) in the Seismic definition so the mass of the pipinsystem is considered in the static and dynamic seismic loading.The AutoPIPE seismic horizontal forces e.g. E1, E2 etc (static seismic 1 etc) at supportswill be added to the corresponding seismic primary load cases as shown above whenthese piping seismic cases are defined as class = primary.
