Vulnerability assessment and loss estimation to simulate the consequences of future earthquakes also rely on damage prediction of buildings. Seismic damage index, which evaluates incremental seismic damage from undamaged to completely damaged condition on a scale from zero to one or more, has been widely used to classify damage to buildings. A well-calibrated seismic damage index also allows the designer of a new building to choose failure mechanisms by supressing undesired failure modes. It can also help to provide rapid evaluation of safety of buildings after an earthquake. In this paper a comprehensive seismic damage index representing complete range of damage and capable of identifying wide range of moderate damage states of RC member has been presented. The parameters of proposed seismic damage index are calibrated by means of observable member damage states featuring specific residual seismic capacity. In this study, the observable member damage states are quantified with extreme fiber compressive strain by simulating experiments in PEER database. Observations from quasi-cyclic analyses of column specimens, covering entire range of member properties, have been used to quantify reduction in strength. The proposed seismic damage index ensures identification of wide range intermediate damage states and represents a significant improvement over prevalent damage indices.
