RCC Structures Design Long and short spans of a two way slab are ly and lx and load on the slab acting on strips parallel to lx and ly be wx and wy respectively. According to Rankine Grashoff theory (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)⁴ None of these (wx/wy) = (ly/lx)² (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)⁴ None of these (wx/wy) = (ly/lx)² ANSWER DOWNLOAD EXAMIANS APP

RCC Structures Design ‘P’ is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The maximum stress ‘f’ in the beam, subjected to a maximum bending moment ‘M’, is f = (A/P) + (M/Z) f = (P/A) + (M/6Z) f = (P/'+ (Z/M) f = (P/A) + (M/Z) f = (A/P) + (M/Z) f = (P/A) + (M/6Z) f = (P/'+ (Z/M) f = (P/A) + (M/Z) ANSWER DOWNLOAD EXAMIANS APP
