RCC Structures Design If the modular ratio is ‘m’, steel ratio is ‘r’ and overall depth of a beam is ‘d’, the depth of the critical neutral axis of the beam, is [m/(m + r)] d [(m + r)/m] d [(r - m)/m] d [m/(m - r)] d [m/(m + r)] d [(m + r)/m] d [(r - m)/m] d [m/(m - r)] d ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design ‘P’ is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The maximum stress ‘f’ in the beam, subjected to a maximum bending moment ‘M’, is f = (P/A) + (M/Z) f = (P/'+ (Z/M) f = (A/P) + (M/Z) f = (P/A) + (M/6Z) f = (P/A) + (M/Z) f = (P/'+ (Z/M) f = (A/P) + (M/Z) f = (P/A) + (M/6Z) 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)/4] h [(p₁ + p₂)/2] h (p₁ - p₂) ⅔h [(p₁ - p₂)/2] h [(p₁ + p₂)/4] h [(p₁ + p₂)/2] h (p₁ - p₂) ⅔h ANSWER DOWNLOAD EXAMIANS APP
