Present work deals with numerical modeling of seismic actions on earth retaining structures. Finite element (FE) analyses have been carried out on scaled-down retaining wall models. The capability of finite element models has been evaluated for the replication of shaking table experiment results. It was observed that FE models are highly sensitive to assigned nonlinear material models, especially for hardening and softening behavior of backfill soil. A detailed and simplified FE modeling procedure is explained for the simulation of seismic actions on earth retaining structures.

Earth retaining walls and bridge abutments are part of the key infrastructure in support of a modern transportation system. Assessment of the structural safety of a retaining wall in seismic conditions is considered in this paper. Present work deals with systematic review of analytical modelling of seismic actions on retaining walls. Experimental investigation for finding displacement demand of scaled down retaining wall models has been discussed. A detailed experimental investigation has been recommended for ensuring the accuracy of the analytical modelling approach.
