INVESTIGATION OF THE BEHAVIOUR OF AN EMBANKMENT DAM UNDER MULTI COMPONENTS NEAR FAULT GROUND MOTIONS

choosing the direction of applied earthquake forces has always been an important issue in earthquake engineering especially as it refers to nonlinear analysis. This is more important in near fault region that directivity effect may occur. In this condition there id big difference between two components of ground of analysis of structures subjected to multicomponents earthquake excitation that enables the designer to find the most critical angle of excitation.
