Introduction

BuildingTcl is a library of Tcl procedures (commands) used to build a database for numerical simulation of building frames. Structural materials, sections, elements, models, analyses, loads and load combinations created in this database. Structural models can be Elevations, Plans, or 3DModels, which combine elevations and plans. Procedures are included to perform the numerical simulation using OpenSees. The OpenSees recorder data is post-processed into more accessible format.

BuildingTclViewer is a Tcl/Tk widget (program) that provides a graphical user interface to create the BuildingTcl database interactively, run the numerical simulations using OpenSees interactively, and view the results interactively.

The user can

  • build a simulation-model library via scripting modules or interactively
  • run simulations via scripting modules or interactively
  • visualize real-time structural response during numerical simulation
  • visualize results interactively.


While BuildingTcl and BuildingTclViewer were developed on a Windows platform, they can be made to work on other platforms, even Mac.


Objectives

  • Generate numerical-simulation input in a manner consistent with architectural/structural drawings
  • Create a database of all structure and simulation data
  • The implementation of OpenSees to do the analysis is natural here, but not restrictive
  • Be able to run on a number of platforms, just as OpenSees can

Download

The BuildingTcl software is now stored using Apache Subversion (SVN) software. SVN provides the means to store not only the current version of a piece of source code, but a record of all changes (and who made those changes) that have occurred to that source code. Use of SVN is particularly common on projects with multiple developers, since SVN ensures changes made by one developer are not accidentally removed when another developer posts their changes to the source tree.

SVN Access

This project can be checked out through anonymous access with the following command (use the dos prompt if on a windows machine).


svn co svn://opensees.berkeley.edu/usr/local/svn/BuildingTcl/trunk BuildingTcl                            

Users of Windows machines are encouraged to look at TortoiseSVN
