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

Quizplus · Accepted Answer

The correct formula for determining the overall depth of a combined footing under a column A, based on punching shear consideration, takes into account the perimeter of the column, the safe punching stress, the load on the column, and any upward pressure acting over the area of the column. This is accurately represented in option B, which correctly incorporates these factors into the calculation.
