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 mc/t = (d - n)/t mc/t = n/(d - n) (t + c)/n = (d + n)/n (m + c)/t = n/(d + n) mc/t = (d - n)/t mc/t = n/(d - n) (t + c)/n = (d + n)/n (m + c)/t = n/(d + n) 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/2 WL/8 WL/4 WL/6 WL/2 WL/8 WL/4 WL/6 ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If p₁ and p₂ are effective lateral loadings at the bottom and top exerted by a level earth subjected to a super-load on the vertical face of height h of a retaining wall, the horizontal pressure p per unit length of the wall, is [(p₁ + p₂)/2] h [(p₁ - p₂)/2] h [(p₁ + p₂)/4] h (p₁ - p₂) ⅔h [(p₁ + p₂)/2] h [(p₁ - p₂)/2] h [(p₁ + p₂)/4] h (p₁ - p₂) ⅔h ANSWER DOWNLOAD EXAMIANS APP
