Question
If the footing 3.5m×3.5m, What is the critical factored shear force considering wide beam action? And If the footing is 3.5m×3.5m, What is the design shear strength of footing considering beam action?
A square footing is proposed to be used to support a 300
mm x 500 mm RC column loaded with 760 kN dead load
and 400 kN live load. The bottom of footing is 1.5 m below
the ground. Assume soil weighs 18.67 kN/cu.m. and
allowable soil bearing pressure is 130 kPa. Thickness of
footing is 500 mm with an effective depth of 410 mm. The
ff data applies:
f'c = 21 MPa
fy = 415 MPa
normal concrete = 23.5 kN/cu.m.
%3D
U= 1.2D + 1.6L
factor for shear = 0.75
