<b></i>Abstract :</b><i><p align=\"justify\"> <br /> The Development of earthquake resistance design of structure in the last decade has been critically changing from \"Strength\" and \"Ductility\" to became \"Performance\", Structural Engineers realize that structural safety does not merely depend on the quantitative strength but it also depends on the performance based ductility demand and energy dissipation involving the corresponding major earthquake. Performance Based Design(PBD) primarily on ductility demand under major earthquake has been considered as a criterion for measuring safety of a structure. The implementation of PBD as a basic design generally using lateral inertia forces induced displacement ductility demand when structures undergo plasticity.<p align=\"justify\"> <br /> Strength and Ductility are not the only criteria of earthquake resistance design of structure but also performance criteria, ATC-40 uses capacity spectrum method to estimate performance of the structure to earthquake. This thesis is a study about Capacity Spectrum methode in estimating structure\'s performance under influence of strong ground motion and its comparison to Dynamic Non-linear Analysis result.<p align=\"justify\"> <br /> To Simplify the problem of in-elastic time history analysis performance based seismic analysis is developed, The Performance Based Design is an equivalent static analysis to assess the in-elastic response of structure during large seismic loading, the PBD as required in ATC-40 has been implemented to study the accuracy of the methode for a single degree of freedom system under several model response, result show that the level of discrepancy is compared to dynamic responses.<p align=\"justify\"> <br /> Art earthquake is a dynamic motion,then analysis tecnique that are compatible to analyze the dynamic response on a structure is non-linear dynamic analysis, however in the applications this analysis is very complicated and not feasible in practicular structure . A simpler option to estimate strength capacities and deformation demands is the non-linear static pushover analysis. Results obtained from the pushover analysis are displacements, ductility, plastic mechanism, behaviour, capacity curve then this results are compared with the results obtained from non-linear dynamic analysis,conclusions based on comparison of the two analysis. <br />
