Paper Abstract

A new coupled vibration control system is proposed for a group of slender buildings constructed closely in urban areas. The connection dampers which can move in vertical, not in lateral are set between the adjacent buildings. Also, to concentrate the earthquake input energy to the connection dampers, a rocking structural system is applied to each connected building. This proposed system can introduce a kind of 'smart' self-centering system for target buildings. To verify the earthquake reduction effects of the proposed system, some numerical analyses are executed to real scale building frame models. In the analyses, two buildings are connected by the vertical dampers. That is the simplest application of the coupled vibration control system. Their responses are compared with those of a single fixed base frame model and a single rocking frame model. The analysis results successfully demonstrated that the new coupled vibration control system has high performance for seismic response reduction of target slender buildings.
