Abstract: Damage states with clear definition, based on the extent of damage and potential failure mechanisms, help reliable decisions regarding reoccupation of the buildings, seismic vulnerability assessment, loss estimation and in developing prioritization schemes for seismic retrofitting of existing structures. The available damage states, defined in terms of measureable engineering parameters (such as crack widths and drifts), have been developed based on experts' opinion and observed damage during earthquakes. The present paper evaluates the correlation between damage state definitions used for damage inspection and crack widths using Pacific Earthquake Engineering Research (PEER) Centre experimental database. It is found that Ohkubo damage state definitions work reasonably well for slender reinforced concrete member, where damage is predominantly due to flexural cracking. The Sinha-Goyal damage state definition, which is based on shear crack widths, is found conservative to classify flexural damage in beam and column elements. The paper also compares the damage states defined in terms concrete compressive strain corresponding to residual cracking, cover spalling and core crushing with the visual damage state definitions, and verifies crack width formulation used to capture damage states of an analytical model.
