A 500mm square pedestal is to be supported by a 2000mm by 3000mm footing. It is to carry a axial dead load of 650 kN and axial live load of 850 kN and a total lateral live load of 150kN acting parallel to longer dimension of footing and 1m from the top of the footing. Thickness of footing is 600mm. Use unit weight of concrete = 24 KN/m3 and unit weight of soil = 18 KN/m3. Use SBC = 350 kPa. (Hint: Moment = Force x distance from the bottom of the footing) Use f'c=28 MPa and fy=415 MPa.
Check for the adequacy of the size in terms of bearing.
Check the adequacy of the thickness in terms of shear (one-way and two-way). Calculate also for nominal one-way and punching shear stress.
Calculate the number 20mm reinforcements. Use steel cover = 95mm.
