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.

Özet

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.
