Abstract In this paper, stiffness based damage index (DI c ) is introduced and expressed as a simple formula based on nonlinear response got from nonlinear static procedures. It is useful because only once the pushover has to be performed for the inertia loads obtained from equivalent static method given in BIS 1893, to show the degree of damage of structure in question. It is employed to the damage assessment of example RC frames representing different structures. To extend DI c for different performance levels defined in FEMA 356, the damage values are related to drift based damage index. Results show that DI c agrees with drift damage values and is valuable tool for practical applications.
