PIPELINK (Workflow 1) AutoPIPE -> STAAD

Open Existing AutoPIPE Model

Analyze for Gravity, thermal, 2 seismic loadings

Import the PIPELINK Model

Into STAAD

Run the Support Connection Wizard to Connection all Supports

to the Structure

Export to STAAD using Pipelink (File > Export)

Open STAAD Model & Select Piping Mode

Workflow 1: Starting in AutoPIPE with Piping Model only

Transfer Piping Loads to Structure

Define STAAD Load Combinations

Open AutoPIPE Model Open Model “Integ_auto1.DAT”

Analyze for Gravity, thermal, 2 seismic loadings Load > Static Analysis Sets

Analyze > Static

View Results – max stress = 67% at Bend C12

Generate AutoPIPE Load Combination Descriptions Tools > Combinations (Select non-code combinations) Select combination options and Generate default non-code descriptions This is useful for the Structural Engineer to understand the AutoPIPE pipe stress loadings

Export to STAAD using Pipelink (File > Export)

PIPELINK File created for Transfer to the Structural Team (MDB file which can be opened in MS ACCESS)

Open STAAD Model Open Model : Integ_sample1.std

Change to Piping Mode Import the PIPELINK Model Mode > Piping, from the Piping Menu , Select Import

Run the STAAD Support Connection Wizard to Connect all or some 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 or unconnected or connected. In this example we will only connect Vstops and Guides.

Next > Select which beams to consider for connection. Can also filter by Section property, groups of beams or saved view screen.

Next > Select which Beam NODES to consider for connection.

Hint: Create new nodes to transfer actual structural displacements to AutoPIPE Connections are made in seconds

Transfer Piping Loads to Structure In Piping Mode, Select Piping > Transfer Loads

This will define the mapping of AutoPIPE load cases to STAAD Primary or Reference load cases. By default class = Reference. For Workflows transferring the Structure to AutoPIPE, it is recommended to set all piping loads 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 cases,

say R1 to R4 for seismic , R5 for the gravity, R6 for pressure, R7 for thermal c. Define the UBC command along with the masses that need to be included,

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 as

seismic (these must be the first load cases in the STAAD file, typically these would be:-

i. +X ii. –X iii. +Z iv. –Z

e. Add the appropriate pipe seismic reference load case to the appropriate primary UBC load case. E.g.

Primary Loadcase

STAAD Loading AutoPIPE

Case Pipe Reference

Case

STRUCT PIPE AND STRUCT +X

UBC X 1.0 E1 R1

STRUCT PIPE AND STRUCT -X

UBC X -1.0 E2 R2

STRUCT PIPE AND STRUCT +Z

UBC Z 1.0 E3 R3

STRUCT PIPE AND STRUCT -Z

UBC 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 seismic loads 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.

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

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....

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

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

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

The sample Tutorial model 1 : Integ_sample1.std Has the following IBC seismic and primary load cases definitions

PIPELINK (Workflow 2) – Multi User

Repeat Workflow 1 for all 4 separate models

PIPELINK (Workflow 3) – STAAD -> AutoPIPE

Open Existing STAAD Model with connected piping system

Analyze for Primary Load Cases

Review Import Logs and resulting structure & connections

Analyze Combined Structure & Piping in AutoPIPE

Export to AutoPIPE using Pipelink (Piping > Export)

Open AutoPIPE Model & Import Pipelink Model

Workflow 3: Starting in STAAD then export the structure to evaluate combined structural and piping stiffness in AutoPIPE

Open Existing STAAD Model Open STAAD model : Integ_sample1.std Analyze STAAD Model

Export to AutoPIPE using Pipelink (Piping > Export)

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/or structural displacements will be updated to the PIPELINK file

Open AutoPIPE Model & Import Pipelink Model

Review Import Logs and Resulting Structure & Connections

Model saved as “INTEG_AUTO1a.DAT” for reference

Open Existing STAAD Model with connected piping system

Analyze for Primary Load Cases

Review Pipe Support Displacements

Export to AutoPIPE using Pipelink (Piping > Export)

Open AutoPIPE Model & Import Pipelink Model

Workflow 4: Starting in STAAD then export the structural displacements to evaluate structural sway on the piping model in AutoPIPE

Re-Run STAAD Piping Connection Wizard

Transfer Piping Loads to Structure

Open Existing STAAD Model with connected piping system Check STAAD model : Integ_sample4.std Re-Run STAAD Piping Connection Wizard Check the option to create new nodes

Hint: Create new nodes to transfer actual structural displacements to AutoPIPE

Transfer Piping Loads to Structure In Piping Mode, Select Piping > Transfer Loads

This will define the mapping of AutoPIPE load cases to STAAD Primary or Reference load cases. Note: Only displacement results for STAAD primary load cases can be exported to AutoPIPE. One Recommendation for defining STAAD displacements to transfer to AutoPIPE is as follows:

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