减振高层建筑的极限破坏及性能再生的研究现状及前景
State-of-the-art and Future Trend in Limit State and Rehabilitation of Vibration-controlled High-rise Buildings
摘要
Abstract
Due to the utilization of high-strength concrete and steel material in building construction,the high-rise buildings are becoming taller and more flexible.In order to supress the structural vibration induced by the earthquakes or winds,the vibration control techniques are getting more applications currently.Howev-er,oil dampers of a steel building had been damaged by the historic great earthquake of East Japan in 2011. This event proved that the dampers have their own limit states,which hasn’t been investigated fully and thor-oughly.In this paper,several damage events of vibration-controlled buildings are reported after the field inves-tigation of 3.11 Earthquake in Japan,including the oil dampers,steel dampers and lead isolators.And the state-of-the-art of current research in the failure process of vibration-controlled system and buildings is summa-rized.The framework of three limit states of vibration-controlled builidings is originally proposed to explore the failure mechanism of controlled structures,considering the coupling effect of the vibration-controlled system and structural mainframe.The key problems lie in the failure mechanism,the performance evolution and the performance-based design /retrofit pholosophy of vibration-controlled builidings.In the near future,more ef-forts needs to be spent in investigating the performance-based theory of controlled high-rise structures and es-tablishing the integrated design and retrofit methodology which incorporates the idea of recoverable and re-placeable dampers.关键词
