［摘要］對(duì)高層結(jié)構(gòu)工程中消能減振設(shè)計(jì)者關(guān)心的設(shè)計(jì)核心內(nèi)容——液體黏滯阻尼器的設(shè)計(jì)與應(yīng)用分五個(gè)部分進(jìn)行了詳細(xì)闡述。其中阻尼器的支撐設(shè)計(jì)內(nèi)容包括套索支撐、剪刀形支撐、跨層支撐、伸臂支撐的介紹及不同支撐形式的對(duì)比；布置設(shè)計(jì)內(nèi)容方面分析了對(duì)剪切位移與層間位移的區(qū)別及阻尼器布置的設(shè)計(jì)方案；參數(shù)設(shè)計(jì)方面闡述了阻尼器的C與α值的選擇策略；阻尼器種類選擇方面介紹了用于抗風(fēng)普通抗震阻尼器、無摩擦金屬密封阻尼器及帶特殊泄壓閥的新型阻尼器；減振設(shè)備的配合設(shè)計(jì)方面介紹了阻尼器與BRB聯(lián)合使用、阻尼器與TMD聯(lián)合使用、阻尼器與摩擦擺聯(lián)合使用及三種配合情況的案例。通過總結(jié)可以看出，消能減振可設(shè)計(jì)的內(nèi)容多且雜，阻尼器支撐形式、布置位置等均可使最終的減振設(shè)計(jì)變得更合理、高效而低價(jià)。

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.

Keywords:energy dissipation; reasonable design; fluid viscous damper; BRB； TMD
