Question

One of the column of a superstructure with a dimension of (cx x cy)mm is shown below.

 

This column need an isolated footing to support its reaction P. The footing width of the footing is constraint due to adjacent footings.

 

The width of the footing must only be B m. Design the isolated footing.

QUESTION 6 One of the column of a superstructure with a dimension of (cx x cy)mm is shown below. This column need an isolated footing to support its reaction P. The footing width of the footing is constraint due to adjacent footings. The width of the footing must only be Bm. Design the isolated footing. The allowable bearing capacity is qa kPa. The compressive strength of concrete is fc MPa while the yield strength of rebar is fy MPa. Use db mm diameter rebar. The unit weight of overburden soil and concrete is ys kN/m3 and yc kN/m3 respectively.
