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 If ‘p’ is the net upward pressure on a square footing of side ‘b’ for a square column of side ‘a’, the maximum bending moment is given by M = pb (b + a)/8 M = pb (b - a)²/8 M = pb (c - a)/4 M = pb (b - a)²/4 M = pb (b + a)/8 M = pb (b + a)/8 M = pb (b - a)²/8 M = pb (c - a)/4 M = pb (b - a)²/4 M = pb (b + a)/8 ANSWER DOWNLOAD EXAMIANS APP
