Abstract

A methodology for calculating the response of structures to earthquakes on specific faults D.B. McCallen, F.E. Heuze, P.W. Kasameyer Lawrence Livermore National Laboratory, Livermore CA, USA ABSTRACT We are developing a methodology chain to estimate the response of structures to large earthquakes from specific faults. The methodology consists of three distinct steps: generation of synthetic bedrock motion at the site of the structure due to a postulated large earthquake; nonlinear effective stress analysis of the soil response at the site to transform bedrock motion to surface motion; and linear/nonlinear finite element analysis of the structure based on the predicted surface motions. Progress in all steps is reported here. INTRODUCTION Our computational simulation of the seismic response of a critical structure is illustrated in Figure 1. To envelope the motions that might be observed at the structure site, the seismologists develop a suite of possible earthquake
