Displaying a Stress Diagram

 

In addition to the Sketch of the beam design we can also display several stress diagrams. Selecting the Diagrams tab will display the Shear/Moment/Deflection diagram shown below.

 

Of special interest are the checkboxes that control the location of live load for the analysis shown in the graphic. Because this program automatically moves the live load around on the beam to obtain the governing values of shear, moment, and deflection on each span for the final calculation results, there really is no single load case that represents the beam analysis.

 

By selecting the live load locations here you can view the detailed stress variations produced by each load application.
