Inelastic Design of Earthquake Resistant Reinforced Concrete Buildings Considering Displacement and Energy Limits

Abstract

In this study, damage assessment of reinforced concrete structures is carried out based on energy response. The damaging potential of earthquakes to structures is estimated by total input energy, which is considered to depend primarily on earthquake property. It is considered that earthquake input energy can be used as the basic value in the earthquake resistant design of RC frames. Generally, damage of structures is estimated by indices based on maximum response, for example, ductility factor or rigidity degrading ratio. However, it is considered that both the maximum displacement and the dissipated hysteretic energy have to be considered in evaluating earthquake damage more appropriately.
