Pounding Of Adjacent RC Buildings During Seismıc Loads

Year 2009, Volume: 22 Issue: 1, 129 - 145, 30.06.2009

Abstract

Turkey is in high seismic risk zone. On a possible earthquake, adjacent buildings


which are not separated from each other properly are under pounding risk. Although gap size


requirements are given in Turkish Earthquake Code (TEC), in Turkey, adjacent buildings are still


been constructing with insufficient gap sizes. In this paper; results of pounding and effects of


pounding to structural elements of buildings are studied. Stress analyses are made on frame models


for different impact points and analysis results are discussed. It is concluded that pounding forces


are not completely absorbable because of their high values but their effects on structure can be


reduced by placing elastic materials between adjacent buildings or by reinforcing structural systems


with cast-in-place reinforced concrete (RC) walls.
