POUNDING MITIGATION USING PALL FRICTION DAMPERS

Pounding is one of the major reasons of structural damages in buildings, constructed very near to each other, when they are subjected to a strong ground motion during an earthquake. In metropolitan cities where buildings have been constructed very near to each other due to high land value and lack of awareness about pounding, pounding mitigation is very necessary for structural safety and life safety. This paper deals with the study of effect of pounding between adjacent buildings having insufficient seismic gap after installation of friction dampers into taller building model. Time history analysis has been done to evaluate the pounding effects for different models of building. The study has shown the effect of pounding on global response of adjacent structures in terms of acceleration, and impact force.
