RCC Structures Design A pre-stressed concrete member is preferred because All listed here Its dimensions are not decided from the diagonal tensile stress Large size of long beams carrying large shear force need not be adopted Removal of cracks in the members due to shrinkage All listed here Its dimensions are not decided from the diagonal tensile stress Large size of long beams carrying large shear force need not be adopted Removal of cracks in the members due to shrinkage ANSWER DOWNLOAD EXAMIANS APP
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 None of these (wx/wy) = (ly/lx)⁴ (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)² None of these (wx/wy) = (ly/lx)⁴ (wx/wy) = (ly/lx) ANSWER DOWNLOAD EXAMIANS APP
