结构被动耗能减振系统的研究与应用大约已有25年的历史。近年来,国内外许多学者都致力于将结构附加耗能或阻尼系统推向实际应用,许多耗能减振装置已经安装在世界多幢土木结构中。已有的主要耗能减振装置大致可分为六类:粘滞型、粘弹性型、金属屈服型、摩擦型、调谐质量阻尼器、调谐液体阻尼器等。本文系统地综述上述六类耗能减振系统的研究与应用进展,内容包括装置的形式、耗能减振机理、分析模型、分析与实验的主要结果、设计方法、实际应用概况和设计规范制定的进展,并指出一些值得进一步研究的方向。
The research and application of passive energy dissipation and vibration damping systems have been around for 25 years. In recent years, many scholars at home and abroad have committed themselves to applying the structure of additional energy-conserving or damping systems to practical applications. Many energy-absorbing and vibration-damping devices have been installed in many earth structures in the world. Existing main energy dissipation and vibration damping devices can be roughly divided into six categories: viscous, viscoelastic, metal yield, friction, tuned mass dampers, tuned liquid dampers, and the like. This article systematically reviews the research and application progress of the above six types of energy dissipation and vibration reduction systems, including the form of the device, the mechanism of energy dissipation and vibration reduction, the analysis model, the main results of the analysis and experiment, the design method, the application overview, and the design specification formulation. Progress and point out some directions for further study.
