EVALUATION OF DAMAGE INDEX OF REINFORCED CONCRETE STRUCTURE AND ITS APPLICATION TO SEISMIC DESIGN

Abstract

The purpose of this study is to define rationally the ultimate limit state of reinforced concrete structure such as pier or column and to propose the damage index which is a rational measurement of safety.
In this study, ultimate limit state due to flexure is defined as the push-out of longitudinal bar, and one due to shear is defined as the yield of shear reinforcement.
Furthermore, new damage index on the basis of these definitions, which are verified by the experimental data, and the method of application of the damage index to the practical seismic design for reinforced concrete structure are proposed.
