In this section, we analyze the model that we currently built to obtain
forces in the STM Elements.
To analyze the model, click Run Design Calculations from the Analysis
menu or click the  button from the Standard toolbar. A window displaying the analysis progress shown in Figure 22 then
appears. After the analysis is completed, the forces for each STM Element are shown in the display window (Figure 23).
In the figure, compression members are represented by dashed blue lines while
tension members are represented by solid orange lines.
Figure 22 The Window Showing Analysis Progress
Notes:
- When there are multiple Load Conditions defined in the model, a dialog box will appear
prior to the analysis progress window, asking for Load Conditions to be
analyzed.
- If you create a Strut-and-Tie Model which is not stable, an error message
indicating that excessive loss of accuracy occurred during the process will
show up. To fix this problem, please follow suggestions described in Q
& A #9.
