- A strip footing is founded on sand having strength parameters (Φ =40⁰ and c = 0 kPa). Dry and saturated unit weights of the soil are 17.8 and 21 kN/m³ respectively. The foundation is designed to to carry a load of 4.8MN/m at a Factor of safety against general shear failure of 3. The footing depth is 1.5 m and the water table is 5 m from the surface.

a) Determine the minimum footing width (m) to satisfy the design requirements (2 d.p). Show all working

b) Is water table affecting foundation support?

c) Is water table affecting foundation support? Verify your assumption. Use unit weight of water of 9.8 kN/m3.

Q2 A concrete strip footing with a width of B is founded at the depth of D, below the surface of a level site. The water table is at a depth of d below the base of footing. The soil at the site consists of clay having the following properties: The unit weight = gt,   the undrained cohesion = cu, the undrained friction angle = fu, the drained cohesion = c′ and the drained friction angle = f′ Use Hansen’s...

In C++ Having call-by-reference allows one to use storeback parameters, i.e., parameters whose values are transmitted back to their arguments. In this exercise, you are to write a program that provides several variations of a function that calculates the minimum of two values. Several of the functions also report whether the two values passed in were equal. The functions are all named min — they differ in their arguments and return values: Accept two integers and return their minimum Accept...
