EFFECT OF POUNDING ON GLOBAL RESPONSES OF BUILDINGS CONSTRUCTED IN A ROW

Pounding is very complex phenomenon and it has been observed very often in metropolitan cities, during an earthquake, where series of buildings in a row without any seismic gaps are in abundance. Due to pounding during strong ground motion, the acceleration at pounding level considerably increases and generates extra pounding force which causes major structural damages or sometime results into building collapse. This paper deals with the study of effects on global response of structures due to pounding during an earthquake. Time history analysis has been done to evaluate the pounding effects for different models of building when subjected to various ground motions into two different cases. The study have shown the effect of pounding on global response of adjacent structures in terms of acceleration, and impact forces which get amplified in many times.
