RCC Structures Design In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed 25 mm 20 mm 15 mm 10 mm 25 mm 20 mm 15 mm 10 mm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design A pile of length ‘L’ carrying a uniformly distributed load ‘W’ per metre length is suspended at two points, the maximum, B.M. at the centre of the pile or at the points of suspension, is WL²/24 WL/8 WL²/16 WL²/47 WL²/24 WL/8 WL²/16 WL²/47 ANSWER DOWNLOAD EXAMIANS APP

RCC Structures Design If C is creep coefficient, f is original pre-stress in concrete, m is modular ratio, E is Young's modulus of steel and e is shrinkage strain, the combined effect of creep and shrinkage is: (1 - C) mf + eE (1 - C) mf - eE (C - 1) mf + eE (C - 1) mf - eE (1 - C) mf + eE (1 - C) mf - eE (C - 1) mf + eE (C - 1) mf - eE 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
