Beam Design

Overview

In the design of concrete beams, the program calculates and reports the required areas of steel for flexure and shear based upon the beam moments,shears, load combination factors, and other criteria described below The reinforcement requirements are calculated at a user-defined number of check/design stations along the beam span

All beams are designed for major direction flexure and shear only Effects caused by axial forces, minor direction bending, and torsion that may exist in the beams must be investigated independently by the user.

Design Beam Flexural Reinforcement

The beam top and bottom flexural steel is designed at check/design stations along the beam span The following steps are involved in designing the flexural reinforcement for the major moment for a particular beam for a particular section:

Determine the maximum factored moments

Determine the reinforcing steel
