【摘要】 地震、风载等灾害荷载作用下,被动振动控制系统耗散了大量的结构振动能量,是最容易破坏的结构关键、敏感部位。由于自身材料为各向异性、多介质耦合、强非线性,因此在复杂时空环境、多因素、多载荷耦合作用下,被动振动控制系统损伤呈现多尺度、多类型特征。本文以叠层橡胶隔震支座和磁流变阻尼器为研究对象,全面综述了当前国内外对这两种结构减隔震系统的性能监测与损伤识别、性能演化与可靠性评估、自适应自供能特性三方面的研究现状,并总结了该研究方面存在的不足,为结构减隔震控制系统性能监测、评估与提升的进一步研究提供了参考。
【Abstract】 Passive vibration control systems, as the key and sensitive components of structures, dissipate a great amount of structural vibration energy under hazard loads such as earthquakes and strong winds etc. The performance of passive control systems degrades in service due to long-term loading and environmental effects. The materials of the passive control systems are characterized as anisotropic, multiple medium coupling and strong nonlinear features, resulting in multi-scale and multiple damages under complex spatio-temporal and coupled loadings conditions. In this paper, literature review regarding performance monitoring and damage identification, performance evolution and reliability evaluation, self-powered and adaptive features of laminated rubber isolation bearings and magnetorheological(MR) dampers are comprehensively presented. The paper also summarizes the shortcomings of the current research, and provides a guideline for further research work of the structural vibration control system, including performance monitoring, evaluation, and development.
