Abstract

The design of the retaining wall requires a complete examination of the wall in static and dynamic conditions. The movement of the wall can be very effective in the analysis and design of the wall. In this paper, numerically and using the ABAQUS/CAE finite element software, seismic performance of the suspended wall under harmonic loading, and under resonant frequency conditions for various factors has been investigated. In this research, various variables, including substrate profile, type of backfill, geometry and wall dimensions, and acceleration and vibration frequency have been investigated. The results of this study indicate that with increasing wall height and denting density, vertical stress and mean of maximum absorbed acceleration decrease, which can be considered in the economic design of the wall.
