RCC Structures Design The load stress of a section can be reduced by Replacing smaller bars by greater number of greater bars Increasing the total perimeter of bars Replacing larger bars by greater number of small bars Decreasing the lever arm Replacing smaller bars by greater number of greater bars Increasing the total perimeter of bars Replacing larger bars by greater number of small bars Decreasing the lever arm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If the length of a combined footing for two columns l meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where x̅ is the distance of centre of gravity of column loads). y = L/2 - (l - x̅) y = L/2 + (l - x̅) y = L - (l - x̅) y = L/2 - (l + x̅) y = L/2 - (l - x̅) y = L/2 + (l - x̅) y = L - (l - x̅) y = L/2 - (l + x̅) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If q is the punching shear resistance per unit area a, is the side of a square footing for a column of side b, carrying a weight W including the weight of the footing, the depth (D) of the footing from punching shear consideration, is D = W (a² - b²)/8a²bq D = W (a² - b²)/4abq D = W (a - b)/4a²bq D = W (a² - b²)/4a²bq D = W (a² - b²)/8a²bq D = W (a² - b²)/4abq D = W (a - b)/4a²bq D = W (a² - b²)/4a²bq 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/8 WL/4 WL/2 WL/6 WL/8 WL/4 WL/2 WL/6 ANSWER DOWNLOAD EXAMIANS APP
