SPH SIMULATION ON SHAKING TABLE TEST OF MASONRY RETAINING WALL

Abstract

 The discrete element method (DEM), the finite element method (FEM) and the discontinuous deformation analysis (DDA) have been applied to earthquake response analysis of masonry retaining walls. However, some difficulties still remains for these methods and an alternative numerical method is required. In this study we applied the Smoothed Particle Hydrodynamics (SPH) to earthquake response analysis of masonry retaining walls by introducing a numerical model of rigid body. A series of shaking table tests were referred and the SPH simulations were conducted. The SPH simulation overestimated the displacement but reproduced the shape of residual deformation of masonry retaining wall after shaking.
