Estimating the seismic pounding force between adjacent buildings and study the effect of gap distance on seismic pounding

Insufficient separation distance between adjacent buildings may lead to their pounding during strong earthquakes causing damage or local failure. Accordingly, most of the design codes specify a minimum gap prevent seismic pounding. Main objectives this research are studying reinforced concrete (RC) under various ground motions and effect on The studied modeled as three-dimensional frames idealize buildings. This study considers frame having same number floors well different floors. Nonlinear finite element time history analysis is performed using ETABS commercial software. Three real earthquake records with characteristics scaled used simulate motion. model at interface points. results indicate that, maximum force was investigated for each cases. Pounding does not occur equal height. Increasing reduces them. Separation distance, which estimated by Egyptian code, conservative.
