SPH Simulation for Seismic Behavior of Earth Structures

Abstract eng:
The earthquake response analysis of earth structures using the Smoothed Particle Hydrodynamics (SPH) was introduced in this paper. We showed that the corrective smoothed particle method (CSPM), which is a modified version of the conventional SPH, could achieve higher accuracy than the conventional SPH for earthquake response analysis. To illustrate this, three numerical simulations were carried out; the one dimensional elastic wave propagation problem with reflection, the earthquake response analysis of the one dimensional elastic soil and the two-dimensional elasto-plastic soil. Finally, we demonstrated the SPH simulation of the collapse behavior of an earth structure.
