Abstract

Numerical analyses have been performed in order to assess the performance of old dock walls under earthquake loading and, if necessary, to develop appropriate remedial measures and check the seismic performance of these. This paper describes the procedures that have been adopted in order to use the numerical analysis program FLAC for time domain analyses. Boundary conditions have been chosen in order to permit synthetic time histories of base motion to be applied to the models. Fills have been modelled as elastic-Mohr-Coulomb frictional materials; concrete and masonry have been modelled as elastic materials, but the inclusion of interfaces representing construction joints or masonry bedding has an important influence on the predicted earthquake response. Remedial measures investigated have included anchors or tension piles at the back of the dock walls and counterforts in front.

Seismic Analysis and Retrofit of Dock Walls

San Diego, California

Numerical analyses have been performed in order to assess the performance of old dock walls under earthquake loading and, if necessary, to develop appropriate remedial measures and check the seismic performance of these. This paper describes the procedures that have been adopted in order to use the numerical analysis program FLAC for time domain analyses. Boundary conditions have been chosen in order to permit synthetic time histories of base motion to be applied to the models. Fills have been modelled as elastic-Mohr-Coulomb frictional materials; concrete and masonry have been modelled as elastic materials, but the inclusion of interfaces representing construction joints or masonry bedding has an important influence on the predicted earthquake response. Remedial measures investigated have included anchors or tension piles at the back of the dock walls and counterforts in front.
