【摘要】：近年來,隨著消能減震技術(shù)的應(yīng)用越來越廣泛,非線性粘滯阻尼器已被廣泛應(yīng)用于工程抗震中。許多國家都相繼制定出臺(tái)了相應(yīng)的消能減震結(jié)構(gòu)設(shè)計(jì)、施工規(guī)范和規(guī)程,我國現(xiàn)行《建筑抗震設(shè)計(jì)規(guī)范》(GB50011-2010)中也增加了消能減震設(shè)計(jì)的規(guī)定,在吸收國內(nèi)外比較成熟的研究成果基礎(chǔ)上,列出了一些關(guān)于消能減震設(shè)計(jì)的原則性條文,但很難為一般的工程師掌握并運(yùn)用于實(shí)際的工程實(shí)踐中。 粘滯阻尼器由于帶有很強(qiáng)的非線性特性,這使得非線性粘滯阻尼器減震結(jié)構(gòu)的分析和設(shè)計(jì)變得更為復(fù)雜和困難。本文就非線性粘滯阻尼器減震結(jié)構(gòu),進(jìn)行了系統(tǒng)的研究,并結(jié)合通用有限元軟件SAP2000,提出了一種實(shí)用的設(shè)計(jì)方法,以使非線性粘滯阻尼器更好的應(yīng)用于工程實(shí)際中。 首先,本文介紹了非線性粘滯阻尼器的構(gòu)造及力學(xué)模型,并從粘滯阻尼器附加阻尼比的公式出發(fā),詳細(xì)介紹了阻尼系數(shù)的設(shè)計(jì)理論和分配理論。 然后,本文第三章對(duì)通用有限元軟件SAP2000進(jìn)行了系統(tǒng)的介紹,將其對(duì)減震結(jié)構(gòu)的模擬、粘滯阻尼器的模擬以及減震結(jié)構(gòu)計(jì)算方法,做了詳細(xì)的說明。證明目前采用SAP2000軟件可以完成對(duì)減震結(jié)構(gòu)的設(shè)計(jì)分析。 在此基礎(chǔ)上,本文提出了一種簡便、實(shí)用、可操作性強(qiáng)的減震結(jié)構(gòu)設(shè)計(jì)方法。該方法從結(jié)構(gòu)的初步設(shè)計(jì)、阻尼器的設(shè)計(jì)、減震結(jié)構(gòu)的分析計(jì)算到附加阻尼比的復(fù)核,形成了一套完整的非線性粘滯阻尼器減震結(jié)構(gòu)設(shè)計(jì)流程,對(duì)一般的工程設(shè)計(jì)人員可很快理解并入手操作。 本文最后得出了一些對(duì)工程有指導(dǎo)意義的結(jié)論,補(bǔ)充和完善了非線性粘滯阻尼器減震結(jié)構(gòu)的設(shè)計(jì)方法,對(duì)工程實(shí)際具有一定意義。
[Abstract]:In recent years, nonlinear viscous dampers have been widely used in engineering aseismic with the application of energy dissipation and damping technology more and more widely. Many countries have formulated the corresponding design, construction code and rules of energy dissipation structure, and the current Code for Seismic Design of buildings (GB50011-2010) has also added the provisions of energy dissipation design. On the basis of absorbing the mature research results at home and abroad, this paper lists some principles of energy dissipation design, but it is difficult for general engineers to master and apply them in practical engineering practice. Due to the strong nonlinear characteristics of viscous dampers, the analysis and design of nonlinear viscous dampers become more complex and difficult. In this paper, the nonlinear viscous dampers are systematically studied, and a practical design method is put forward in combination with the general finite element software SAP2000, so that the nonlinear viscous dampers can be better applied in engineering practice. Firstly, the structure and mechanical model of nonlinear viscous dampers are introduced, and the design theory and distribution theory of damping coefficient are introduced in detail from the formula of additional damping ratio of viscous dampers. Then, in the third chapter, the general finite element software SAP2000 is introduced in detail. The simulation of the damping structure, the simulation of the viscous damper and the calculation method of the structure are described in detail. It is proved that the design and analysis of shock absorption structure can be completed by using SAP 2000 software. On this basis, a simple, practical and operable design method of shock absorber structure is presented in this paper. From the preliminary design of the structure, the design of the damper, the analysis and calculation of the shock absorption structure to the check of the additional damping ratio, a set of complete design flow of the nonlinear viscous damper structure is formed. General engineering designers can quickly understand and start to operate. Finally, some conclusions of guiding significance are obtained, which complement and perfect the design method of nonlinear viscous dampers, which is of certain significance to engineering practice.
