RCC Structures Design If l₁ and l₂ are the lengths of long and short spans of a two way slab simply supported on four edges and carrying a load w per unit area, the ratio of the loads split into w₁ and w₂ acting on strips parallel to l₂ and l₁ is w₁/w₂ = (l₂/l₁)³ w₁/w₂ = l₂/l₁ w₁/w₂ = (l₂/l₁)⁴ w₁/w₂ = (l₂/l₁)² w₁/w₂ = (l₂/l₁)³ w₁/w₂ = l₂/l₁ w₁/w₂ = (l₂/l₁)⁴ w₁/w₂ = (l₂/l₁)² ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design ‘P’ is the pre-stressed force applied to tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The minimum stress ‘f’ on the beam subjected to a maximum bending moment ‘M’ is f = (P/A) - (M/6Z) f = (A/P) - (M/Z) f = (P/'- (Z/M) f = (P/A) - (M/Z) f = (P/A) - (M/6Z) f = (A/P) - (M/Z) f = (P/'- (Z/M) f = (P/A) - (M/Z) ANSWER DOWNLOAD EXAMIANS APP
