SEISMIC ANALYSIS OF ADJACENT BUILDINGS WITH POUNDING EFFECT

Abstract

During major earthquakes, pounding between two adjacent structures will be an important phenomenon which may cause severe damages to the structures. Structural components of those pounded structures will be greatly damaged during earthquake excitation. Insufficient distances between the structures are the main reason for the pounding effect. To mitigate the effect of the pounding the simplest form is to provide maximum separation distance to the structures. Thus, it is very important to find out the pounding effect of two closely spaced structures during an earthquake excitation. Non-linear seismic analysis has been done to investigate the effect of pounding damage between the two MDOF adjacent buildings subjected to ground motion and the time history analysis has been used for this paper. The results are observed in the form of story shear, story drift and displacement which are helpful to find the occurrence of pounding between the two structures.
