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 Based on punching shear consideration, the overall depth of a combined footing under a column A, is (Perimeter of column A × Safe punching stress)/(Load on column A × Upward pressure × Area of the column) (Area of the column A × Safe punching stress)/Load on column A None of these (Perimeter of column A × Safe punching stress)/(Load on column A + Upward pressure × Area of the column) (Perimeter of column A × Safe punching stress)/(Load on column A × Upward pressure × Area of the column) (Area of the column A × Safe punching stress)/Load on column A None of these (Perimeter of column A × Safe punching stress)/(Load on column A + Upward pressure × Area of the column) ANSWER DOWNLOAD EXAMIANS APP
