In this section, several advanced examples are presented to demonstrate how to model structures in fire using OpenSees. Thermo-mechanical analysis Restrained beam subjected to temperature rise Single beam subjected to temperature rise compared to a real test Composite beam example Steel frame example The example also. demonstrates how an analysis object is 'built' from component objects. subsection { Example 1.1 } This example is of a linear-elastic three bar truss, as shown in. figure~ ef { example1 }, subject to static loads. space {0.2in} oindent { f Files Required} 1. Select an existing OpenSees model file (.tcl) and import its geometry in GiD. 2. Run analysis and postprocess (same to toolbar button) 3. Just create the .tcl file. 4. Create the .tcl file and Appendix A - User's Guide to Opensees A.1 Introduction to Using OpenSees The Open System for Earthquake Engineering Simulation (OpenSees) is a software framework created for the analysis of structural and geotechnical systems subjected to earthquakes. The code for the OpenSees software is open source, or freely available to •OpenSees.exe is an extension of the Tcl interpreter for finite element analysis which uses this framework. It is an example of an application that can be developed using the framework. What is Tcl User Manual 2008 ver 1.0 (Earlier versions of the user manual: 2005, 2004, 2003) Examples. Note: The examples below are compatiable with the latest version of OpenSees (ver 2.2.0). For examples working with earlier versions (from ver 2.0.0 to ver 2.1.0), OpenSees interpreter. Notice should be taken that OpenSees is dimensionless, so the user must make sure that he uses a consistent system of units (e.g. SI). Once an example.tcl file has been created, the user can then simply run OpenSees.exe, and in turn, write in the command line of the interpreter "source example.tcl" to run his analysis. Dear OpenSees Navigator users, Thanks for your interest in OpenSees Navigator. This program is intended to be self-explanatory, nevertheless a basic user manual will be added to the website shortly. We are very happy to have the opportunity to distribute this software for OpenSees Navigator users. We encourage everyone to try out all of the The OpenSees Command Language Manual. The OpenSees Command Language Manual. Version 1.2. August 20, 2001. Frank McKenna and Gregory L. Fenves. This, for example, could be the displacement history at a node in a transient analysis or the entire state of the model at each step in the solution procedure. Several Recorder objects are created by
