Question

300 mm thick footing slab supports a 300 mm thick wall carrying uniform service dead load of 214.31 kN/m and service live load of 145.9 kN/m. The base of the wall footing slab is 1.2 m from the ground surface.Design parameters are as follows: γsoil = 16 kN/m3, γconc = 24 kN/m3, qa = 215.46 kPa, f’c = 27 MPa and fy = 420MPa. 

1.Calculate the net allowable bearing capacity of soil in kPa.

2.Calculate the minimum required width of the wall footing slab.

3 Calculate the maximum ultimate moment (kNm) in the slab if the width of footing slab is 2.1 m

4 Calculate the required center to center spacing of 16 mm bars for flexure if the maximum factored moment in thr slab is 75 kN-m

5 Calculate the ultimate beam shear stress on the footing slab if the footing slab is 2.1 m wide.
