4 For the square Footing shown in the figure below Calculate net allowable bearing capacity of the foundation shown in the figure below. Note: The foundation is square footing with width of (4 m). (asSume a safety factor = 3.0) GWT 1.5 m 4.0m Sand 2.0 m Ø-35°, Vzat=17.5kN/m², Clay c=50 kN/m², =18.5 kN/m',

We are interested in the forces at a footing due to dead, live, and earthquake loads. The horizontal forces are 0.6 for dead, 0.9 for live, and 4.9 for earthquake. The vertical forces are 2.5 for dead, 3.7 for live, and 3.8 for earthquake. For vertical forces, positive indicates compression and negative indicates uplift. Apply all the relevant load combinations. All forces are in kips.   Determine the largest compressive vertical force in kips to two decimals.

A concrete square footing 1.5 m x 1.5 m has a total depth of 500 mm. It supports a rectangular column 300 mm x 400 mm. If the allowable normal stress of concrete is 4 MPa. What is the maximum axial load (in kN) the column can carry? Do not include units in final answer. Answer in 3 decimal places. A concrete square footing 1.5 m x 1.5 m has a total depth of 425 mm. It supports a rectangular column 300 mm x 280 mm. If the punching shear strength of concrete is 2.2 MPa. What is the maximum axial load (in kN) the column can carry? Do not include units in final answer. Answer in 3 decimal places.
