EVALUATION OF DAMAGE INDEX OF REINFORCED CONCRETE STRUCTURE

Abstract

In this study, new method of evaluation of damage index of reinforced concrete member of which ultimate limit state is reached by flexural-compression after yielding is proposed. Accumulative consumed energy of member is thought to be a total energy consumed during earthquake motion. While, maximum consumed energy is a specific value for each member and is determined by the dimension of section and material properties. Proposed damage index is examined by available test data.
Furthermore, we show the procedure for applying proposed damage index to seismic design of reinforced concrete structure in the lignt of reliability approach.
