TS 500 One-Way Slab Reinforcement

Flexural reinforcement per meter width of slab, governed by the largest of: required strength, TS 500 minimum ratio, and TS 500 slab-specific minimum. Includes maximum bar spacing.

Inputs

Design moment per meter M_d kN·m/m

Effective depth d mm

TS 500 §7.1Singly-reinforced flexure: Md = 0.85·fcd·b·a·(d−a/2), As·fyd = 0.85·fcd·b·a — same equations as a 1m-wide beam strip.

TS 500 §7Slab-specific minimum reinforcement ratio and maximum spacing rules apply on top of the general beam minimum.
