Abstract

Although this problem arises frequently in design practice, there is little guidance for the designer in current literature. The proposed method entails estimating the free-field soil deformation caused by a horizontal acceleration. Dynamic increase in earth pressure against an (effectively rigid) wall is assumed to be proportional to the free-field deformation, relative to the base of the wall, with an upper limit equal to full passive pressure. Dynamic pressures calculated using this method are compared with field evidence from published records of observations made on a building in Yokohama during an earthquake.

A Simple Method of Estimating Seismic Pressures from Cohesive Soils Against Basement Walls

St. Louis, Missouri

Although this problem arises frequently in design practice, there is little guidance for the designer in current literature. The proposed method entails estimating the free-field soil deformation caused by a horizontal acceleration. Dynamic increase in earth pressure against an (effectively rigid) wall is assumed to be proportional to the free-field deformation, relative to the base of the wall, with an upper limit equal to full passive pressure. Dynamic pressures calculated using this method are compared with field evidence from published records of observations made on a building in Yokohama during an earthquake.
