Q14.

How are STM Node shapes constructed in CAST?

The shape of an STM Node is simply formed by the intersection of Effective Widths of Struts and Ties framing into that STM Node. Stresses in the Node, along with its Stress Ratios, fc' Ratios, and Beta Ratios, are reported at each side of the Node shape.

To show stresses in an STM Node:

Right-click the Node on the display window. The STM Node Info dialog box similar to Figure 14.1 will be displayed.
To obtain the information on a Node side stress, select the Node side ID from the Node Side combo box. Alternatively, click the Node side on the image of the dialog box.
To show all Node side stresses together, click the Show Table button. The STM Node Stress Info dialog box similar to Figure 14.2 will show up.
