Abstract: Many parameters affect the behavior of tall buildings under seismic loads, some of which are the main shock-after shock records and using some lateral load resistance systems in reinforced concrete tall buildings. End shear walls are a kind of shear walls, connecting their end in tall buildings. This study was conducted on two 30-story reinforced concrete structures, which were subjected to sequences of far fault records and analyzed by the nonlinear time history analysis. The results indicated a 51% decrease in maximum inter-story drift in 30 stories with end shear walls under sequence records. The normal Q-Q plots (quantile-quantile plot) presented approximately 20% reduction in the excepted normal domain in X and Y directions, respectively, in 30 stories with end shear walls. The kurtosis coefficient declined by 61 and 92% in the X and Y directions in 30-story structure end shear walls, respectively. Therefore, the end shear wall increased the confinement effects by decreasing the dispersion data of inter-story drift and improving seismic behavior.
