Damage Prediction Models for Reinforced Concrete Buildings Based on Non-Linear Analysis with Consideration to Soil-Structure Interaction

Abstract eng:
It is very important to construct analytical models that can express the actual seismic strength of buildings in order to estimate the damage to buildings for future earthquakes. Nagato and Kawase (2004) created such models by comparing building damage ratios based on the statistical damage survey for RC (reinforced concrete) buildings affected by the Hyogo-ken Nanbu earthquake and results from nonlinear response analyses of building models assumed under current building codes using simulated strong input 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 a result, more appropriate models are proposed, especially for 9 and 12 storied RC buildings.
