RCC Structures Design The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation. m = 700/3C m = 1400/3C m = 2800/3C m = 3500/3C m = 700/3C m = 1400/3C m = 2800/3C m = 3500/3C 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/4 WL/2 WL/6 WL/8 WL/4 WL/2 WL/6 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 10 mm 15 mm 20 mm 25 mm 10 mm 15 mm 20 mm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If the permissible compressive and tensile stresses in a singly reinforced beam are 50 kg/cm² and 1400 kg/cm² respectively and the modular ratio is 18, the percentage area At of the steel required for an economic section, is 0.696 % 0.496 % 0.596 % 0.796 % 0.696 % 0.496 % 0.596 % 0.796 % ANSWER DOWNLOAD EXAMIANS APP
