Determination Of Seismic Bearing Capacity Of Strip Footings Using Krey's Method

Bearing capacity failures due to earthquake have detrimental effects. In geotechnical investigation,determination of the seismic bearing capacity of shallow foundation is very important. Due to seismicloading foundation may experience decreases in bearing capacity and increases in settlement. In thepresent paper, a theoretical analysis has been performed on the basis of Krey's method with radius offriction circle where it is the radius circle slip surface to determine the influence of the earthquakeacceleration coefficients on the seismic bearing capacity of foundation with assisted by a computerprogram. The seismic forces are considered as pseudo-static forces acting on the soil under the footing.Finally,The results obtained from the present method are compared with results of other Researchers
