Nonlinear Lateral Performance of Skew Abutments

The lateral force-deflection relationship between an abutment backwall and the retained soil or Concrete Low Strength Material (CLSM) can significantly affect bridge performance. The current inventory of test data that can be directly applied to develop design guidelines is limited to backwalls with zero skew and backfill materials consisting of well compacted clay or silty sand. Testing and simulation tools are needed for other common conditions such as various non-zero skew angles and amounts of torsional rotation as well as CLSM backfill.
