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.
