Code check of the general purpose prismatic cross section defined in the STAAD.Pro analysis package is not available. The prismatic section is assumed to be a rectangular massive box and the von Mises stress is checked at 3 locations as shown in figure below.
Note: Note that
"b" may not
be much greater than
"h". If that is the case, define the member with h > b and
beta angle 90° instead.
