RCC Structures Design If W is total load per unit area on a panel, D is the diameter of the column head, L is the span in two directions, then the sum of the maximum positive bending moment and average of the negative bending moment for the design of the span of a square flat slab, should not be less than WL/10 (L - 2D/3)² WL/12 (L - D/3)² WL/10 (L + 2D/3)² WL/12 (L - 2D/3)² WL/10 (L - 2D/3)² WL/12 (L - D/3)² WL/10 (L + 2D/3)² WL/12 (L - 2D/3)² 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
