Design an isolated square footing:
P(dead load) = 550 kN
P(live load) = 375 kN
M(dead load)= 125 kN-m
M(live load)= 40 kN-m
Qa = 220 kPa
Df = 2.0 m
Unit wt. of concrete = 23.5 kN/m^3
Unit wt. of soil =18.0 kN/m^3
Bar diameter = 25 mm
f`c = 27.6 MPa
fy = 414 MPa
Assume height of footing = 500 mm (check adequacy, if failed - increase the depth)
Use min. cover = 75 mm
Determine the following:
(a) Effective Soil Bearing Pressure, Qe
(b) Footing Dimensions
(c) Maximum and Minimum Soil Bearing Pressure (Qumax & Qumin)
(d) Check for Shear Criteria (Beam Shear)
(e) Check for Shear Criteria (Punching Shear)
(f) Required Steel Area or Number of Rebars
