The document outlines the design specifications for reinforced rectangular beams according to NSCP 2010, detailing dimensions, design parameters, and calculations for two different beam configurations. It includes steps for determining beam type (SRB or DRB), evaluating tension control, and calculating factors such as ultimate moment and reinforcement area. The document provides specific values for beam dimensions, material strengths, and design results for each beam scenario.
