A strip foundation with dimensions B has to be constructed on sandy soil. The foundation will be located at 1 m below the ground surface. The unit weight and the static angle of friction of the soil are 18 kN/m3 and 39o , respectively. The foundation may occasionally be subjected to a maximum dynamic load of 1800 kN increasing at a moderate rate. (i) Determine the size of the foundation using a safety factor of 3 by assuming the kh and kv values are 0.176 and 0, respectively. (ii) Determine the seismic settlement of the foundation if the design earthquake parameters are V = 0.4 m/sec and A = 0.32.
