ALL CALCULATIONS MUST BE SHOWN 1. The 16 columns (represented by dark circles) shown in Figure 1 carry a distributed load of 250+3Y) kPa imposed by the roof and slabs of the building that they support. It has been decided to design the mat footing, also shown in Figure 1, to support the above columns. The other geometrical information is shown below: Center to center spacing of columns = 3 m Distance from the edges of the footing to the centers of the corresponding peripheral columns = 0.5m Depth of the footing in the ground = 1.1 m Mean SPT 55 of the foundation soil = (20+0.25Y) (a) Check whether this footing size is adequate (08 points).
