     providing the strength and ductility capacities for new buildings have been the most important factors in the current seismic design code which is based on force-based design approaches. the design objectives in current building codes address life safety performance level, control damage in minor and moderate earthquakes, and prevention collapse in a major earthquake. after the severe damage originated in the past disaster earthquake ground motions, the need for revision in current seismic design codes has been recognized. in the two past decades, the concept of performance-based seismic design [pbsd] has been initiated and grow up for seismic rehabilitation of existing building and at present time quantified in some famous regulations for assessment and evaluation of old non-ductile building e.g. fema-273, 356 and asce-41. however the mentioned procedure has been not detailed for design of new buildings. recently some countries published standard or pre-standard regulation on using pbsd for practical design of building. the key important concern in pbsd procedure is design criteria corresponding to different performance levels. current design codes normally uses drift ratio for accepting performance criteria in life safety level and no local or global design criteria introduced in different performance levels. currently study focuses on investigation of performance criteria which is introduced by researchers or advanced design codes which involved pbsd procedures in design of new buildings e.g. taiwan, turkey, and etc. in this research the relationship between local and global design criteria are also discussed. drift ratio as a global and number of yielded elements as local design criteria will be processed. finally the results will be compared with empirical design criteria and new design codes.
