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/6Z) 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) 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 WL²/47 WL²/16 WL²/24 WL/8 WL²/47 WL²/16 WL²/24 WL/8 ANSWER DOWNLOAD EXAMIANS APP
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 10 mm 15 mm 25 mm 20 mm 10 mm 15 mm ANSWER DOWNLOAD EXAMIANS APP
