RCC Structures Design

Q1: A simply supported beam , 6 m long and of effective depth 50 cm, carries a uniformly distributed load 2400 kg/m including its self weight. If the lever arm factor is 0.85 and permissible tensile stress of steel is 1400 kg/cm2, the area of steel required, is

A 14 cm2

B 15 cm2

C 16 cm2

D 17 cm2

E 18 cm2

ANS:C - 16 cm2

Ast = M/0.85(tensile stress * lever arm * depth).
M = wl^2/8,
Ast = 15.725.
