Damage prediction models for reinforced concrete buildings based on non-linear analysis with soil-structure interaction

Abstract

It is very important to construct analytical models that can express the actual seismic strength of buildings in order to estimate the damage of building against the future earthquakes. Nagato and Kawase (2001) create such models by comparing the building damage ratios based on the damage statistics of RC (reinforced concrete) buildings during the Hyogo-ken Nanbu earthquake and those of the nonlinear response analyses of buildings models assumed from the current building code using simulated strong motions. In this paper, Nagato's models are improved by considering both the effect of amplification of the earthquake motion in the surface sediments and the effect of the soil-structure interaction. As the results, more appropriate models are proposed, especially for 9" and 12-storied RC buildings.
