Shear FY, Shear FZ
Enter these values on the Beam Section Definition dialog box for general sections if you are interested in examining the exact effects of shear on a beam. These factors represent the ratio of a beam's effective "shear area" to its true cross-sectional area for shear in the principal Y and Z directions.
You must enter a positive value for each of these properties. If you leave this value blank:
• Native mode assigns the default value of 0.833333, which is accurate for rectangular cross sections.
• FEM mode interprets the value as undefined.
For L and channel sections, the default value is section-specific.
