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 20 mm 25 mm 15 mm 10 mm 20 mm 25 mm 15 mm 10 mm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design According to load factor method, the permissible load ‘W’ on a short column reinforced with longitudinal bars and lateral stirrups, is Stress in steel × area of steel Stress in concrete × area of concrete + Stress in steel × area of steel Stress in concrete × area of concrete None of these Stress in steel × area of steel Stress in concrete × area of concrete + Stress in steel × area of steel Stress in concrete × area of concrete None of these ANSWER DOWNLOAD EXAMIANS APP
