|Title||GROUND MOTION PARAMETER MAP FOR PALESTINE: SEISMIC DESIGN BASED ON IBC 2012|

ABSTRACT This thesis includes the development of spectral response accelerations maps and risk coefficient maps for Palestine according the international building code (IBC 2012). The maps were developed for 5% damped acceleration response spectrum having a 2% probability of exceedance within a 50 year (2475 return period) in short (0.2 second) and long period (1 second). The probability seismic hazard analysis method has been used to develop the maps by using the (EZ-FRISK) software program. Thirty seismic sources have been identified and characterized using appropriate seismic parameters. The parameters of the area seismic zones determined from the historical earthquakes category. An empirical ground motion model was used due to limited ground motion data in Palestine. The developed maps were compared to Israeli and Jordanian maps for 2% probability of exceedance within a 50 year in short and long period with 5% damping. The comparison of Israeli and developed maps shows the similarity in the maps with limited difference in magnitude in the north-east of Palestine by 30% more than the developed maps. There are some differences between Jordanian and developed maps in long period which about 70% more than the developed in the eastern boundary of Palestine, while in the short period maps the magnitude are similar. A total of 16 multistory residential with five and fifteen stories in Gaza and West Bank have been used as a case study for comparison purposes. The seismic forces in the case study were calculated according to different codes (UBC97, IBC2012 with Jordan and developed maps, Israeli code SI413 2013). The calculated forces in the case study due to different codes are variable; the UBC97 result was the smallest forces in each case by decreasing from the developed forces about 10% and 30% in multistory and residential in Gaza, respectively while in Jericho 7% and 15% in multistory and residential, respectively. The Jordan maps result similar forces in Gaza cases, while in Jericho the Jordan maps result forces more than developed maps by 39% and 23% in multistory and residential, respectively. In Palestine most of designers use UBC97 in design because lake of spectral maps according IBC 2012. The final recommend in the thesis to use the developed maps and design according the IBC 2012 to be more conservative and to save the lives and building in Palestine.
