Basic Study on Development and Validation of Seismic Response Analysis Using High-Fidelity Model for Large-Scale Reinforced Concrete Structures

Abstract

A seismic response analysis method using high-fidelity model for large-scale reinforced concrete structures is being developed. In this research, implementation of a constitutive relation of concrete and an appropriate model contraction method for reinforced concrete structures are described. Especially, implementation of the constitutive relation of concrete which is suitable for conjugate gradient method is important. We show the performance of the developed method using analysis of loading tests of a reinforced concrete structure. We also show the convergence check of analysis of reinforced concrete structures as basic validation of the developed method. We finally apply above method to a seismic response analysis of a simple nuclear power plant building model and discuss applicability of the method.
