Abstract

Retaining walls have suffered damages under past earthquakes. Usually the analyses do not consider the retained soil’s interaction with the wall, which takes place during dynamic conditions. The consideration makes the wall-soil system more flexible than the wall alone. The conditions of separation of wall (during interactions) again change the dynamic characteristics of the assumed wall-soil system that needs to be addressed. The paper presents a study on the behavior of the retaining wall under static as well as seismic conditions considering above aspects. The wall-soil interaction model incorporates the modeling of interface between them. The system is idealized as a plane strain twodimensional model and base acceleration in the form of typical earthquake motion (Uttarkashi, October 20, 1991, India) is represented as external loading. The study concludes with important results, which are useful for researchers, scientists and those involved in analyses and design of retaining walls.

Effects of Wall-Soil-Structure Interaction on Seismic Response of Retaining Wall

San Diego, California

Retaining walls have suffered damages under past earthquakes. Usually the analyses do not consider the retained soil’s interaction with the wall, which takes place during dynamic conditions. The consideration makes the wall-soil system more flexible than the wall alone. The conditions of separation of wall (during interactions) again change the dynamic characteristics of the assumed wall-soil system that needs to be addressed. The paper presents a study on the behavior of the retaining wall under static as well as seismic conditions considering above aspects. The wall-soil interaction model incorporates the modeling of interface between them. The system is idealized as a plane strain twodimensional model and base acceleration in the form of typical earthquake motion (Uttarkashi, October 20, 1991, India) is represented as external loading. The study concludes with important results, which are useful for researchers, scientists and those involved in analyses and design of retaining walls.
