Knowing that the structure exerts a uniform pressure of 200 KN/m2 on the surface of the soil and dimensions of the foundation 100x70 (m), calculate the load applied on the foundation.

Which of the following is type of Shear Failure: Strip footing, Strap foundation, Local shear failure, Global shear failure, Pile failure?

Back

Local shear failure

Front

Deep foundations rely on ….

Back

end bearing and skin friction

Front

In this type of failure, footing penetrates into the soil without any bulging in the soil at the surface.

Back

Punching

Front

Which of the following are some characteristics of shallow foundations? 1-They are easier to construct. The construction process of shallow foundations is more complex. 3-They transfer loads mostly by end bearing 4-They rely both on end bearing and skin friction, with few exceptions like end-bearing pile. 5-Construction materials are available, less labor is needed, construction procedure is simple at an affordable cost, etc.
