     design or rehabilitation of structures lead to objective performance levels in accordance with owners and codes selections. for this purpose, performance levels consist of target building performance level definitions and selection of an anticipated earthquake hazard levels. operational, immediate occupancy, life safety and collapse prevention are considered as performance levels with dependent structural and nonstructural damages. damages of building under seismic load conduct to loss description of each performance levels. incremental dynamic analysis (ida), is one of best method that describe response of structures to seismic loads from elastic to nonlinear and dynamic instability. using of earthquake time histories, nonlinear models and dynamic analysis of structure lead to increase accuracy of this method. by appling ida to structure and definition of performance levels for variable values of intensity measures, im, probability of occurrence of performance levels are described. also with definition of cost for achieving to each performance levels of structure and contribution of calculated occurrence probability of considered performance levels, lead to have loss estimation. loss estimation are used for decision of owners and code criteria definitions to achieving desired performance. in this case of study by definition of performance levels on ida curves and loss curve, loss conditioned for ims are described.
