BuildingTcl Commands

Most BuildingTcl Library commands consists of a series of parameter-defining add-Data commands, concluded by an add-Object command, which takes the previously defined parameters and assembles them into an individual library object.

  • SET UP

source myBuildingTcl.tcl

<setDataDir Data>

<setUnits -Length $BasicLengthUnit -Force $BasicForceUnit -Time BasicTimeUnit>

  • DEFINE INPUT DATA

addMaterialData …..

addMaterial ; # define Materials Library


addSectionData …..

addSection; # define Section Library


addElementModelData …..

addElementModel; # define ElementModel Library


addAnalysisModelData …..

addAnalysisModel; # define AnalysisModel Library


addModelData …..

addModel; # define Model (Elevation, Plan, 3DModel) Library

addLoadData ….. addLoad; # define Loads Library


addLoadCombinationData …..

addLoadCombination; # define LoadCombination Library

The following commands are Building-Tcl specific. They are used to run the OpenSees simulation.

  • BUILD AND ANALYZE

SelectModel …..

SelectLoadCombination …..

BuildAndAnalyze


Run BuildingTcl

  • myBuildingTcl.tcl – no graphics
- Incorporates BuildingTcl commands into the Tcl Interpreter
- The BuildingTcl commands are used within OpenSees.exe or OpenSeesTk.exe.

1. Run from OpenSees Prompt: 

a. Run OpenSees.exe or OpenSeesTk.exe
b. Source myBuildingTcl.tcl at OpenSees prompt
c. Source input and analysis files at OpenSees prompt


Run BuildingTclViewer

  • myBuildingTclviewer.tcl – BuildingTcl with graphical interface
- Incorporates BuildingTcl & BuildingTclviewer commands into the Tcl/Tk Interpreter 
- This file needs to be sourced from the OpenSeesTk.exe prompt, or by double-clicking on the BuildingTclViewer.bat file

1. Run from OpenSees Prompt: 

a. Run OpenSeesTk.exe – a Tk window opens up (do not close it).
b. Source myBuildingTclviewer.tcl at the OpenSees prompt 
- -- the Tk window becomes the BuildingTclviewer

Or 2. Double-click on myBuildingTclviewer.bat


Getting-Started Input File

This file contains all the input data for the building model and simulation. It can be used by both BuildingTcl and the BuildingTclViewer.

GettingStartedInputFile.tcl -– Setup & Materials

GettingStartedInputFile.tcl -– Run
