Performance Test Of Lead-Visoelastic Damper And Studies On Design Method For Energy Disiipation Stucture

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...
