BuildingTcl

BuildingTcl is a library of Tcl procedures (commands) used to build a database for numerical simulation of building frames. Structural model, loading and analysis data are included in this database. Additional procedures are available to perform the numerical simulation using OpenSees.

BuildingTclViewer is a Tcl/Tk widget (program) that provides a graphical user interface to view the BuildingTcl database, run the numerical simulations using OpenSees interactively, and view the results interactively.* Generate numerical-simulation input in a manner consistent with architectural/structural drawings

Objectives 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

High-level scripting tool Generate building-model data Materials Sections Element Types Analysis Models Loads (Gravity & Lateral) Load Combinations Models Elevations Plan 3D Frames Generate analysis-model data Generate loading and load-combination data Create OpenSees model of building Perform OpenSees numerical simulations Post-Process OpenSees recorder output into formatted data Generate OpenSees input files

Graphical User Interface (GUI) for BuildingTcl Generate and/or visualize ALL BuildingTcl input graphically Save ALL input into BuildingTcl script Perform numerical simulations using OpenSees interactively Visualize OpenSees simulation real-time Pause and/or stop OpenSees analysis real-time Visualize simulation results interactively Export simulation results

Tcl/Tk:

• Tcl is the scripting language used by OpenSees.exe. It runs on Windows, Unix and Macintosh platforms.
• Tk is the graphical user interface toolkit associated with Tcl.
• Tcl/Tk Commands
