CIVL 7119/8119 Earthquake Engineering SAP 2000 Tutorial for Analyzing Trusses The following is a step-by-step procedure for analysis a two-dimensional truss structure using SAP 2000. The order of some of these steps is not critical; however, all step should be completed before execution of the analysis. If you have any questions, or you find any of these instructions unclear or inaccurate, please contact Shahram Pezeshk (spezeshk@memphis.edu). To help students become familiar with some of the numerous aspects and features of SAP 2000, the following tutorial will focus on determining the forces in each member of the roof truss shown below. Assume all members are pin connected. When you select New Model on the menu, the Coordinate System Definition window will appear (see the figure on the right). Remember, that SAP 2000 assumes that your two- dimensional structure resides in the x-z plane. Define your grid system by entering data on the Coordinate System Definition window. For the truss shown above, the the grid spacing in the x and z- directions is 20 feet. The number of grid spaces in the x and z-directions are 4 and 1, respectively. No y-direction grid line are necessary for this problem. When you click OK , SAP 2000 generates the grids line you have just defined and shows you the grid system in the SAP 2000 interface window. By default SAP 2000 show two views of your problem, typically a 3-D view and an x-y plane view. To adjust the views, select an window and click on the appropriate view button located along the top edge of the interface window….
