完全弾塑性体の消散エネルギーに基づいたRC部材の損傷度評価

Abstract

In this paper, new method of damage evaluation of reinforced concrete beam of which ultimate limit state is reached by shear failure after yielding under reversed cyclic loading such as earth-quake motion is proposed. The proposed method is based on dissipated energy of perfectly elasto-plastic body. In the proposed method, revision factor is adopted in order to consider the influence of cyclic loading at the same displacement on damage. The damage of reinforced concrete beams of which ultimate limit state is reached by shear failure after yielding is quantitatively evaluated and the proposed method is shown to be reasonable.
