［摘要］对高层结构工程中消能减振设计者关心的设计核心内容——液体黏滞阻尼器的设计与应用分五个部分进行了详细阐述。其中阻尼器的支撑设计内容包括套索支撑、剪刀形支撑、跨层支撑、伸臂支撑的介绍及不同支撑形式的对比；布置设计内容方面分析了对剪切位移与层间位移的区别及阻尼器布置的设计方案；参数设计方面阐述了阻尼器的C与α值的选择策略；阻尼器种类选择方面介绍了用于抗风普通抗震阻尼器、无摩擦金属密封阻尼器及带特殊泄压阀的新型阻尼器；减振设备的配合设计方面介绍了阻尼器与BRB联合使用、阻尼器与TMD联合使用、阻尼器与摩擦摆联合使用及三种配合情况的案例。通过总结可以看出，消能减振可设计的内容多且杂，阻尼器支撑形式、布置位置等均可使最终的减振设计变得更合理、高效而低价。

Abstract:Design and application of fluid viscous dampers(FVD), which is the core content that concerned by energy dissipation designer of the high-rise structure, was discussed for five sections in detail. The support design of the damper included the introduction of the toggle brace, the scissor brace, the cross-layer brace, the outrigger brace, and the comparison of different brace forms; in terms of layout design, the difference between shear displacement and inter-layer displacement and the layout design of damper were analyzed; in parameter design, the selection strategy of values of C and α of the damper was described; in terms of the selection of dampers, the common dampers used for wind resistance, frictionless metal seal dampers and new type dampers with special pressure relief valves were introduced; the combination use of damper and BRB, damper and TMD, damper and friction pendulum were introduced. It can be seen from the summary that the contents of energy-dissipated design have many complicated ways, and the support form and layout position of the damper can make the final energy-dissipated design more reasonable, efficient and cheaper.
