STAAD.Pro is capable of performing concrete design based on the South African code SABS-0100-1 2000 Code of Practice for Structural Use of Concrete Part1: Design. Design can be performed for beams (flexure, shear, and torsion) and columns (axial load + biaxial bending). Given the width and depth (or diameter for circular columns) of a section, the program calculates the required reinforcement.
