Lecture 1: Beam Analysis

Analyze the beam shown in figure using STAAD Pro and get support reactions and draw the SFD and BMD.

Steps:

1. Open STAAD Pro input the file name and units and click next.

2. Now select add beam and click finish.

3. Now close the snap node window and input the nodes of the beam.

4. Now connect the nodes by selecting add beam command.

5. Now select the support command. Then click create command and add two new support= hinge and roller as following the figure.

7. Select the assigned supports and then click on use courser to assign and Assign them to nodes.

8. To see the dimension of the beam click on tools-dimension beams and display.

9. Now Select property command and click define and define the beam property as desired.

14. If the loading line is invisible or too small you can reduce the scale factor as follows.

15. You can also view the load values from the diagram command. Be clicking load values.

16. Now select the Analysis / Print command and add.

19. If the diagram is invisible or too small you can reduce the scale factor as shown.

20. From the node command and reaction- you can see the support reactions.

21. You can also see the individual AFD, SFD and BMD by selecting the beams from the graph command.
