The aim of the study is to investigate the seismic behavior and consequences in the action of different near ground motions using the HAZUS methodology, of a shear wall RC structure. It has been observed that different characteristics of the near fault ground motion such as, the normal distance from fault trace  or the distance from point source, is different from far fault ground motion.

In this present work, a 8 storey shear wall building, has been performed the push over and time history analysis’. The damage limit state has been defined according to the HAZUS methodology and the pushover analysis, for checking the performance level and the limit states using the SAP 2000 software. To quantify the maximum displacement of the building, we  used the existing seismic records in a non-linear time history analysis.  Therefore the Hazus results had been in tabulated in this thesis, evaluated and plotted against a fragility curve, case that gives the  probability of exceedance of damage limit states of the aforementioned building.

After this step, we look for the differences between the Hazus methodology and the SAP limit states,  which in this case, it resulted that the differences between HAZUS methodology and SAP 2000 limit states were way too small or inexistent .
