Description: This guide provides simple rules for designing reinforced concrete beams of span/depth ratio below 2 for single spans or 2.5 for multiple spans. Supplementary rules deal with cases where load capacity of the beam may be affected by elastic instability, where loads are concentrated, or where holes in the beam may affect performance. The derivation of the rules is given. Appendices give typical stress distribution in deep beams, design examples, buckling strength, shear strength of top-laded deep beams, and an estimate of deflections in deep beams.
