RCC Structures Design The system in which high tensile alloy steel bars (silica manganese steel) are used as pre-stressing tendons, is known as C.L. standard system Freyssinet system Lee-McCall system Magnel-Blaton system C.L. standard system Freyssinet system Lee-McCall system Magnel-Blaton system ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design As per IS : 456, the reinforcement in a column should not be less than 0.7% and not more than 7% of cross-sectional area 0.8% and not more than 8% of cross-sectional area 0.6% and not more than 6% of cross-sectional area 0.5% and not more than 5% of cross-sectional area 0.7% and not more than 7% of cross-sectional area 0.8% and not more than 8% of cross-sectional area 0.6% and not more than 6% of cross-sectional area 0.5% and not more than 5% of cross-sectional area ANSWER DOWNLOAD EXAMIANS APP
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 (t + c)/n = (d + n)/n (m + c)/t = n/(d + n) mc/t = n/(d - n) mc/t = (d - n)/t (t + c)/n = (d + n)/n (m + c)/t = n/(d + n) mc/t = n/(d - n) 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 15 mm 20 mm 25 mm 10 mm 15 mm 20 mm 25 mm 10 mm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If ‘W’ is the load on a circular slab of radius ‘R’, the maximum radial moment at the centre of the slab, is WR²/16 2WR²/16 5WR²/16 3WR²/16 WR²/16 2WR²/16 5WR²/16 3WR²/16 ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The maximum shear stress (qmax) in a rectangular beam is 2.0 times the average 1.50 times the average 1.25 times the average 1.75 times the average 2.0 times the average 1.50 times the average 1.25 times the average 1.75 times the average ANSWER DOWNLOAD EXAMIANS APP
