SAP2000 presentation What is SAP2000? SAP2000 is a general purpose finite element program which performs the static or dynamic, linear or nonlinear analysis of structural systems. It is also a powerful design tool to design structures following AASHTO specifications, ACI and AISC building codes. These features, and many more make SAP2000 the state-of-the-art in structural analysis program. The SAP2000 graphic user interface (GUI) is used to model, analyze, design, and display the structure geometry, properties and analysis results. The analysis procedure can be divided into three parts: 1. Preprocessing. 2. Solving. 3. Postprocessing Part I Preprocessing: In preprocessing, the following information is needed by SAP2000. 1. Choosing the units for this project. 2. Setting up geometry. 3. Defining material and member section properties. 4. Assigning member section properties and element releases. 5. Defining load cases. 6. Assigning load magnitudes. 7. Assigning restraints. PART II Solving In this part SAP2000 will assemble and solve the global matrix. PART III Postprocessing. The main options in postprocessing are: 1. Displaying the deformed shape. 2. Displaying the member forces. 3. Printing the results. 4. Designing the structural members and checking the safety of a design. Solve the problem using SAP2000 About SAP2000 v17 : The Software is available to all engineering students during open lab hours (Room E344). You can also download an evaluation version from http://www.csiamerica.com Step 1: Begin a New Model Start SAP2000 from File menu > New Model command or the New Model button. - Unit: The form shown in Figure will display. Verify that the default units are set to lb, in, F. When a new model is started, SAP2000 will ask the user to specify a set of units. Those units become the “base units” for the model. Grid Spacing - Determine the appropriate number of grid line and grid spacing to locate the joints of the truss. Click on Grid only from the set of templates. Once your joints are restrained, is time to assign the applied load. To apply the load, first select the node where it is to be applied, and go to Assign -> Joint Loads -> Forces. The Joint Forces window shows Load Pattern Name and the different axes. Assign the type of load applied to the truss by entering the value of the load in the proper direction, taking in consideration the axes used in the model. On the Load Pattern Name drop down menu, click on the plus sign to add a new load type for load applied. On the Define Load Patterns window, click on the Load Pattern Name box and type a name for the load, for example LIVE, change the type on the next box to LIVE, and then click on Add New Load Pattern. Then click Ok. For this example, the load is applied in the negative direction of z, with a magnitude

11. Click this point
Then drag up to the next joint, click that point

12. This line will now appear, to remove the draw mouse press Escape button
Now, make two beam support at each end. Both roller and hinge
Go to Assign > Joint > Restraints

13. Select or click the first joint and click the Hinges icon then apply
Then select the next joint and click the Roller icon then apply

14. This will be the figure of the beam with supports

15. Now select the beam
And go to Assign > Frame Loads > Point Load

16. The 5kN load is at the center of the beam
In relative distance it is 0.5
Then click Apply

17. After applying the load, run now the beam
Go to Analyze > Run Analysis

18. Then click Run Now

19. The beam will deform like this
And click the Start Animation (located bottom right)
