Response evaluation and analysis using impulse of base-isolated buildings during a collision with retaining wall

Abstract

The objective of this study is to examine the effect of the base-isolated buildings during a collision with retaining wall using a shaking table and to evaluate by numerical simulation. First, the factors that influence the response of superstructure during a collision were identified from the experimental results. And, an appropriate process was proposed for the evaluation of story shear force. Second, time history analysis using impulse was proposed. This method could not only reproduce the response of superstructure during a collision, but also indicate the possibility to predict it without using collision analysis.
