is the official supplementary handbook published by the Bureau of Indian Standards (BIS) to streamline the design process for reinforced concrete structures. Its primary objective is to reduce manual calculation time for complex clauses in the IS 456:1978 code , particularly for beams, slabs, and columns. Key Content & Scope

: Design charts (interaction diagrams) for rectangular and circular columns subjected to axial load and bending moments.

The handbook provides extensive charts and tables for both and Working Stress Method :

: Tables for determining the shear strength of concrete and calculating stirrup reinforcement.

: Specific aids for deflection calculations and ensuring control of cracking.

Each section of the handbook typically follows a standardized format to ensure clarity for the designer: SP 16: Design Aids for Reinforced Concrete to IS 456:1978
