"A footing may fail in shear as a wide beam". Explain this statement ?
Calculate the ultimate bearing capacity considering the following. A strip footing, 2 meters wide A square footing 3 m by 3 m A circular footing 3 m in diameter All footings are located at the ground surface and groundwater levels is at the ground surface. The soil is coarse-grained with saturated unit weight of 19.8kn/m3 and angle of internal friction 25°.
The structural engineer for this building has determined that the columns will be circular, and each will carry a load of 130 tons (1 ton = 2000 Ibs.). You are asked to design a square footing that will be placed 5 feet below the ground surface in sand. The sand has an effective unit weight of 73 lb/ft? and an angle of shearing resistance of 30 degrees. The water table is at the ground surface. Assume a factor of safety of three.
SITUATION. A 3 mx 3 m square spread footing is to support a 350 mm x 350 mm column carrying a dead load of 750 kN and live load of 500 kN. For concrete f'c is 21 MPa and for steel, fy is 415 MPa. If the effective depth of the footing is 500 mm, find the number of 25 mm reinforcements. O O 13 12 10 11 9
