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.

The present study deals with the drift and displacement capacities of reinforced concrete (RC) bridge abutments subjected to seismic excitations. Two dimensional (2D) finite element (FE) analyses have been conducted to investigate the behavior of the bridge abutment taking into account dynamic actions of the backfill in seismic conditions. The capability of scaled down bridge abutment models is also investigated in order to replicate the dynamic behavior of prototype bridge abutments. The analyses have taken into account interactions between the abutment and the backfill, which can significantly affect the seismically induced displacement behavior of the bridge abutments. It was observed that scaled down bridge abutment models could effectively replicate the seismic behavior of prototype bridge abutments. The stiffness of the bridge abutment degrades significantly with increasing intensity of ground motion. The location of the point of rotation of the bridge abutment is almost constant irrespective of the height of the stem wall. Drift and displacement behavior of the bridge abutment is highly controlled by the thickness of the stem wall.
