Simply Supported Reinforced Concrete Beam Analysis and Design (ACI 318-14)
Simply supported beams consist of one span with one support at each end, one is a pinned support and the other is a roller support. The ends of these beams are free to rotate and have no moment resistance. There are numerous typical and practical applications of simply supported beams in buildings, bridges, industrial and special structures.
This example will demonstrate the analysis and design of the rectangular simply supported reinforced concrete beam shown below using ACI 318-14 provisions. Steps of the structural analysis, flexural design, shear design, and deflection checks will be presented. The results of hand calculations are then compared with the reference results and numerical analysis results obtained from the spBeam engineering software program by StructurePoint.
