Transcribed Image Text:A footing supports a 250 mm thick concrete wall
Given:
Service Axial Load = 331 kN/m
Concrete, f'c = 20 MPa
Steel, fy = 415 MPa
Width of Footing 2.06 m
Thickness of Footing 300 mm
Cohesion = 16.62 kPa
Unit weight of soil = 16.68 kN/m³
Saturated unit weight of soil = 20.24 kN/m
Depth of the footing 2.10 meter
Depth of GWT from the bottom of footing 0.51 meter
Friction angle = 20 degrees
Calculate the gross factor of safety, Use Terzhagi's bearing equation.
