【摘要】：消能減震技術(shù)是一種結(jié)構(gòu)控制技術(shù),是通過在結(jié)構(gòu)的適當(dāng)位置安裝消能減振裝置,利用這些裝置的耗能來減小結(jié)構(gòu)在強(qiáng)震下的振動(dòng)反應(yīng)。黏滯阻尼器就是一種性能優(yōu)良的消能減振裝置。針對(duì)既有框架結(jié)構(gòu)抗震加固中采用黏滯阻尼器的消能減震技術(shù)進(jìn)行了分析和研究,主要工作如下:1)總結(jié)相關(guān)的力學(xué)模型及其耗能原理,嘗試概括并歸納在消能減震這一理念中的設(shè)計(jì)方法,歸納其具體步驟,探索適用的詳細(xì)準(zhǔn)則以及相應(yīng)的計(jì)算分析方法。并且總結(jié)概括了黏滯阻尼器在結(jié)構(gòu)中布置時(shí)的優(yōu)化理念,論述了其相關(guān)的優(yōu)化設(shè)計(jì)方法以及控制函數(shù)的選擇。2)結(jié)合既有工程結(jié)構(gòu)模型,采取層間位移為控制函數(shù),利用ETABS和MIDAS有限元分析軟件,多次試算優(yōu)化布置阻尼器。3)通過比較層間剪力和位移角,計(jì)算并且分析加設(shè)黏滯阻尼器和無黏滯阻尼器的無控結(jié)構(gòu)的抗震性能,體現(xiàn)黏滯阻尼器較好的抗震能力。以我國(guó)發(fā)行的《建筑抗震設(shè)計(jì)規(guī)范》為對(duì)比依據(jù),宗旨便是在對(duì)消能減震設(shè)計(jì)這一理念進(jìn)行闡述的同時(shí),對(duì)這一領(lǐng)域中的理論研究進(jìn)行概括總結(jié),并通過既有框架結(jié)構(gòu)實(shí)例的應(yīng)用研究,表明黏滯阻尼器良好的減震性能,以此推進(jìn)進(jìn)一步的推廣和發(fā)展。
[Abstract]:The energy dissipation technology is a kind of structure control technology, which can reduce the vibration response of the structure under the strong earthquake by installing the energy dissipation device in the proper position of the structure and utilizing the energy dissipation of these devices to reduce the vibration response of the structure under the strong earthquake.Viscous damper is an excellent energy dissipation device.This paper analyzes and studies the energy dissipation and seismic absorption technology of existing frame structures using viscous dampers. The main work is as follows: 1) summarize the relevant mechanical models and their energy dissipation principles.This paper attempts to summarize and sum up the design method in the idea of energy dissipation and seismic absorption, summarizes its concrete steps, and explores the applicable detailed criteria and corresponding calculation and analysis methods.The optimization idea of viscous damper in the structure is summarized, and the related optimization design method and control function selection. 2) combined with the existing engineering structure model, the interstory displacement is taken as the control function.By using ETABS and MIDAS finite element analysis software, the aseismic performance of uncontrolled structures with viscous dampers and non-viscous dampers is calculated and analyzed by comparing the shear forces and displacement angles between layers.The viscous dampers have better seismic performance.Based on the "Code for aseismic Design of buildings" issued in China, the purpose is to summarize the theoretical research in this field while expounding the concept of energy dissipation design.Through the application research of the existing frame structure, it is shown that the viscous damper has good vibration absorption performance, which can promote the further promotion and development.
