NONLINEAR DYNAMIC ANALYSIS METHOD FOR REINFORCED CONCRETE SHEAR WALLS OF REACTOR BUILDINGS CONSIDERING THE STRAIN RATE EFFECTS ON SKELETON CURVES

Abstract

Nonlinear dynamic analysis methods for reinforced concrete shear walls of reactor buildings are proposed. In the methods, the strain rate effects are considered on skeleton curves of the shear walls. The effects are re-evaluated based on test results. The proposed methods are applied to the simulation analysis of shaking table tests of the reinforced concrete shear walls. The calculation results by the proposed method show better agreement with the test results than the calculation results from the conventional method do.
