Abstract

A simplified kinematic method to compute seismic earth pressures against structures with restrained horizontal displacements is described. The retaining structure has a linear elastic behavior and the retained soil is considered linear as well as a nonlinear material. Seismic pressures for different maximum free field accelerations were obtained by applying free field horizontal displacements at the base of the interaction springs connecting the soil and the retaining structure. For perfectly rigid structures without horizontal displacements and linear retained materials, seismic pressures obtained with the simplified kinematic method are compared with those obtained using elastic models; for nonlinear retained soils comparisons are established with results obtained using the finite element method. Finally, a parametric analysis was performed using the kinematic method with nonlinear soils for both perfectly rigid and flexible retaining structures with restrained horizontal displacements.

Seismic Earth Pressures Against Structures with Restrained Displacements

St. Louis, Missouri

A simplified kinematic method to compute seismic earth pressures against structures with restrained horizontal displacements is described. The retaining structure has a linear elastic behavior and the retained soil is considered linear as well as a nonlinear material. Seismic pressures for different maximum free field accelerations were obtained by applying free field horizontal displacements at the base of the interaction springs connecting the soil and the retaining structure. For perfectly rigid structures without horizontal displacements and linear retained materials, seismic pressures obtained with the simplified kinematic method are compared with those obtained using elastic models; for nonlinear retained soils comparisons are established with results obtained using the finite element method. Finally, a parametric analysis was performed using the kinematic method with nonlinear soils for both perfectly rigid and flexible retaining structures with restrained horizontal displacements.
