The aim of this study is to correlate the seismic performance of a real RC frame structure at different levels
with the inadequate separation gap against pounding with an adjacent same height structure. Seismic pounding damage
is the most common phenomena among the possible building damage during seismic excitation. Therefore it is imperative
to consider pounding effects for structures. To understand the seismic behavior of structures, non-linear finite elements
analysis is carried out for pounding of adjacent structure having same heights. The results were obtained in the form of
storey shear, pounding force, storey displacement, storey drift and acceleration. The acceleration significantly increases
during collision of buildings. Pounding produces more shear at the different storey location than the no pounding case.
Increasing gap between two structures will decreases the storey shear of respective structures. The damage assessment
can be carried out by the obtained pounding force. The result shows for the different time history data of India. The
modeling and analysis done in CSI ETABS v16.2 software package.
