【摘要】 结构振动控制是一种新型的抗震技术，利用耗能器进行结构减震就是一种有效的被动控制方法，能有效的减小建筑结构的风振和地震反应。因此，国内外已有越来越多的专家投入到此方面进行研究，并已取得了一些成果，但在新型阻尼材料和阻尼器的开发研究、阻尼器的性能、阻尼结构的分析和设计等方面仍然存在很多问题，有待进一步解决完善。 本文对新型的铅粘弹性阻尼器进行了性能试验，建立了其的恢复力曲线模型，在此基础上结合耗能减震控制技术的研究成果，建立了耗能减震结构的设计方法，给出了具体算例，并对铅粘弹性阻尼器在一项实际工程中的应用进行了分析说明。全文共分为五章。 第一章回顾总结了耗能减震控制技术的研究现状和存在问题，阐明了本课题的目的、意义以及研究的内容。 第二章对粘弹性阻尼器和铅粘弹性阻尼器进行了性能试验，以考察阻尼器的耗能性能和各影响参数对其性能的影响规律。 第三章研究论述铅粘弹性阻尼器的几种力学模型，给出模型中参数的确定方法，从描述阻尼器耗能准确性和合理性的角度对比两种模型的优缺点。 第四章从能量的角度阐述了耗能减震设计的原理，提出了设计准则，给出了耗能减震结构抗震设计的统一方法，并以两个算例进行说明，最后对铅粘弹性阻尼器在一项实际工程中的应用进行分析论述。 第五章作为全文的结论和展望，指出了文中有待解决的问题和本课题的进一步研究、发展方向。 由于耗能减震结构设计设计的内容较广，加之本文作者的能力有限，文中定会存在一些缺点和错误，敬请各位学者和专家批评指正。更多还原

【Abstract】 Structure vibration control is a new kind of anti-earthquake technique. Structural damping by energy dampers is one of effective passive control methods and can effectively reduce structure’s wind vibration and earthquake response. So at home and abroad more and more experts study on energy dampers, and acquire many achievements, but there are many problems about new damping material and damper’s study, the mechanical ability of dampers, damping structure’s analysis and design etc., so these problems require to be solved and completed.In this paper, the properties of new damper -lead viscoelastic damper are experimental studied, and its mechanical model is also founded. Based on the achievements of energy dissipation we establish the analysis design method about energy dissipation structure and give an example. There are 5 chapters in this thesis. Chapter 1 reviews the present state and problems about energy dissipation techniques. Meanwhile, the significance and contents of this paper are introduced.Chapter 2 according to the results of experiment on viscoelastic damper and lead- viscoelastic damper, the effects of the laws concerning different parameters on the behavior of the damper are obtained.Chapter 3 based on several mechanical models which are used to analyze the mechanical abilities of LVED, two lands of mechanical models which used to analyze the mechanical abilities of LVED are compared.Chapter 4 explains the principle of energy dissipation in the view of energy, gives the design code and unified method for energy dissipation struture by two examples, finally states a real engineering which uses the LVED.Chapter 5 the conclusions, problems and future research topics of this item are summarized.In this thesis, due to writer’s poor knowledge, there must be some faults and shortcomings in the paper.Any Suggestions and Critics are Welcomed更多还原
