Specifications of Input Motions for Seismic Analyses of Soil-Structure Systems within a Nonlinear Analyses Framework. Final Report

摘要

A brief assessment of some rational approaches to specifying input motions within a nonlinear analysis framework is presented. Using a modified STEALTH 1D seismic and SHAKE computer codes, some points discussed in the assessment are illustrated. The cases studied in this project are confined to seismic environments with the wave field to consist of vertically propagating body waves, and the site to be horizontally layered. Under this seismic condition, it is possible to specify the control motion either (a) at an outcrop of the baserock, or a given soil layer at some depth, or (b) at the surface of the site profiled.
