compute - one of the orthogonal directions is assumed to
be parallel to the design section.
c. Punching shear check. This design is performed for all
rectangular columns satisfying the following conditions:
- The column supports the slab at a node located within
a design panel or on its boundary,
- There are no beams attached to the common slab-
column node.

Technical Overview
Interactive slab design in STAAD.Pro is based on a prior finite
element analysis (FEA) of the entire structure. The analysis allows
to get accurate values of internal forces for the model, including
component plate elements of the slab. As with any FEA project,
