Research Trends Of Self-centering Passive Damping System
Recently passive damping system has been widely applied. One of the main drawback of the passive damping system is that the high levels of deformation reached during the earthquake implies the presence of residual inter-story drifts at the end of the seismic event, which can result in the complete loss of efficiency of the structure, causing a reconstruction cost possibly higher than the value of the building itself. In order to mitigate such problems, self-centering structural systems have recently been developed. This type of system is characterized by the presence of a self-centering force that mitigate, and at least eliminate, the residual deformations of the building after the earthquake. The purpose of this study is to investigate of the research trend of self-centering seismic structural system.
