Pounding Hazard Reduction Using a Coupling Strategy for Adjacent Buildings


Abstract eng:
Buildings’ pounding is described as the collision between adjacent buildings resulting from certain excitations, and more specifically seismic excitations. Avoiding pounding is a significant challenge especially in metropolitan areas where these buildings are built very close to each other, and where the coast of land is very high. This work aims to reduce the risk of pounding between two adjacent buildings by using a coupling strategy of two adjacent structures with a passive damper used in the control of seismic vibrations. Adopting a coupling strategy allows to transform the two separated structures into one system coupled by a damping device, which result in a synchronised vibrating mode between the two coupled structures. Because of coupling, the structures move in the same direction during the earthquake, this will avoid any unsynchronised vibrations that can cause a potential pounding hazard situation. This can be achieved by using a passive damping device. In this study, two structural configurations presenting a high pounding risk are investigated for this study. It has been found that chances of pounding are reduced along with a reduction regarding top floor displacement. In addition, it has been also observed that the use of a single damping system at the top floor reduces responses and avoids pounding of adjacent buildings.
