11th Week Day 5

Done some column checking on the drawing as the orientation of pile cap should be in correct direction with the column to get optimum distribution of both forces and moments.

For pile cap with 2 piles, we should always put the pile cap parallel with the column to ensure both the piles will receive equal forces from the column.

For Pile cap with 3 Piles, we should put the orientation of pile cap as below because the C.G. of the Force will be at the C.G. of the triangle, giving more stable distribution of forces.

For Pile cap with 4 piles or more, We will put the pile cap according to the pile dimension , whichever longer will go with the longer side while whichever shorter will goes for the shorter side
