Objective

To find the section properties, flexure capacity, and moment curvature of the reinforced concrete beam.

Reference

SAP2000 v.19.0.0 Section Designer

Problem

A rectangular beam has the dimensions (see Figure 7.4.1.1) b = 12 in., h = 20 in., and reinforced with four No. 9 bottom bars and two No. 9 top bars with concrete cover of 1.5 in. The concrete strength f'c is 4000 psi and the yield point of steel fy is 60,000 psi.
