Abstract
The research aims to evaluate the impact of pounding on neighboring buildings, both those with eccentric and non-eccentric configurations, and provide valuable recommendations for seismic design. To achieve this, a numerical simulation is conducted to calculate the effects of pounding on the seismic response requirements in a specific scenario where two irregular adjacent buildings (one is eccentric and the other is non-eccentric) are considered. Different combinations of scenarios are employed to create various cases of irregular adjacent buildings, including both eccentric and non-eccentric configurations. These cases involve multi-story buildings with four, eight, and twelve stories, utilizing a moment-resisting frame (MRF) system. To ensure the accuracy of the analysis, three different ground motions are applied to these unique adjacent building cases, all of which are fully compatible with the design spectrum. To evaluate the response demands of different eccentric and non-eccentric adjacent buildings, a nonlinear time history analysis is performed. This analysis assesses various response variables such as displacement, story drift, story shear force responses, fundamental period and acceleration. These response variables are thoroughly examined to gain a comprehensive understanding of the structural behavior and performance of the irregular adjacent buildings.
