RCC Structures Design If ‘A’ is the sectional area of a pre-stressed rectangular beam provided with a tendon pre-stressed by a force ‘P’ through its centroidal longitudinal axis, the compressive stress in concrete, is P/2A A/P P/A 2A/P P/2A A/P P/A 2A/P 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)⁴ (wx/wy) = (ly/lx)² None of these (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)⁴ (wx/wy) = (ly/lx)² None of these (wx/wy) = (ly/lx) ANSWER DOWNLOAD EXAMIANS APP
