【摘要】：近年來,隨著消能減震技術的應用越來越廣泛,非線性粘滯阻尼器已被廣泛應用于工程抗震中。許多國家都相繼制定出臺了相應的消能減震結構設計、施工規(guī)范和規(guī)程,我國現(xiàn)行《建筑抗震設計規(guī)范》(GB50011-2010)中也增加了消能減震設計的規(guī)定,在吸收國內外比較成熟的研究成果基礎上,列出了一些關于消能減震設計的原則性條文,但很難為一般的工程師掌握并運用于實際的工程實踐中。 粘滯阻尼器由于帶有很強的非線性特性,這使得非線性粘滯阻尼器減震結構的分析和設計變得更為復雜和困難。本文就非線性粘滯阻尼器減震結構,進行了系統(tǒng)的研究,并結合通用有限元軟件SAP2000,提出了一種實用的設計方法,以使非線性粘滯阻尼器更好的應用于工程實際中。 首先,本文介紹了非線性粘滯阻尼器的構造及力學模型,并從粘滯阻尼器附加阻尼比的公式出發(fā),詳細介紹了阻尼系數(shù)的設計理論和分配理論。 然后,本文第三章對通用有限元軟件SAP2000進行了系統(tǒng)的介紹,將其對減震結構的模擬、粘滯阻尼器的模擬以及減震結構計算方法,做了詳細的說明。證明目前采用SAP2000軟件可以完成對減震結構的設計分析。 在此基礎上,本文提出了一種簡便、實用、可操作性強的減震結構設計方法。該方法從結構的初步設計、阻尼器的設計、減震結構的分析計算到附加阻尼比的復核,形成了一套完整的非線性粘滯阻尼器減震結構設計流程,對一般的工程設計人員可很快理解并入手操作。 本文最后得出了一些對工程有指導意義的結論,補充和完善了非線性粘滯阻尼器減震結構的設計方法,對工程實際具有一定意義。
[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.
