RCC Structures Design In a doubly-reinforced beam if ‘c’ and ‘t’ are stresses in concrete and tension reinforcement, ‘d’ is the effective depth and ‘n’ is depth of critical neutral axis, the following relationship holds good (t + c)/n = (d + n)/n mc/t = n/(d - n) mc/t = (d - n)/t (m + c)/t = n/(d + n) (t + c)/n = (d + n)/n mc/t = n/(d - n) mc/t = (d - n)/t (m + c)/t = n/(d + n) 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 None of these (wx/wy) = (ly/lx) (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 ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If the length of a wall on either side of a lintel opening is at least half of its effective span L, the load W carried by the lintel is equivalent to the weight of brickwork contained in an equilateral triangle, producing a maximum bending moment WL/4 WL/6 WL/8 WL/2 WL/4 WL/6 WL/8 WL/2 ANSWER DOWNLOAD EXAMIANS APP
