Abstract

<p>This paper describes analysis models that can reproduce historical characteristics of RC columns during large deformation. Inorder to continue to use RC buildings hit by a severe earthquake, it is essential to suppress not only damage to the skeleton but also residual deformation. Furthermore, analysis models that can reproduce the hysteretic characteristics of RC members in detail are required for more appropriate evaluation of residual deformation. In this paper, new analysis models that combine two multi-springs with different hysteretic characteristics are proposed. The analysis results using these analysis models can accurately reproduce the experimental results of RC columns on complicated loading protocols.</p>
