EFFECT OF SEISMIC POUNDING BETWEEN ADJACENT BUILDINGS AND MITIGATION MEASURES

Puneeth Kumar M S, S Karuna

Abstract: During earthquakes the buildings closely spaced have a chance of pounding on the adjacent building block. In present day scenario buildings are constructed very close each other in urban areas for the complete usage of limited land space. So in this study attempt was made to analyse the seismic response due to pounding between the buildings that are constructed without sufficient separation gap. A model of two buildings closes to each other one being G+ 10 storey and other being G+7 storey were considered. The parameters like displacement and impact force were considered for the analysis using SAP 2000 software. Mitigation measures are provided using lateral load resisting system such as bracings and shear wall. The objective of the study was to find the best practical solution for buildings subjected to seismic pounding under high seismic zone.

Keywords: Bracings, impact force, pounding, SAP2000, shear wall, time history analysis.
