The order of some of these steps is not critical; however all step should be completed before execution of the analysis. If you haveany 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. Page 2When you start SAP 2000 Educational Version 6.10 you should see the following interface window: Page 3Page 4Step 1: Set Problem Dimensions On the bottom on the interface window set the desired units for the problem using the pulldown menu. In this example the units are feet and kips.Step 2: Grid Spacing Determine the appropriate number of grid line and grid spacing to locate the joints of the truss. The grid spacing is set by defining a new problem. To create a new problem select New Model under the Filemenu. Page 5Page 6When 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 twodimensional structure resides in the xz 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 zdirections is 20 feet. The number of grid spaces in the x and zdirections are 4 and 1 respectively. No ydirection 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 3D view and an xy plane view. To ...
