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)² (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 ANSWER DOWNLOAD EXAMIANS APP
