Research Of Isolation Effect For Tanghan Expressway Project, Yongdingxinhe Bridge

Yongdingxinhe main bridge adopt concrete structure and has great weight, the level of the related components that produced by seismic forces is considerable, especially on the basic trick it is difficult to bear. this paper with high Intensity down to the shock and structure of numerical analysis of the basic theoretical basis, combining modern structure of the technology to achieve the following research content:. (1) the finite element analysis of the software design from the shock as the reaction of nonlinear analysis, and will, there is no reduction of the shock of the results in contrast, in theory the reduction of the shock of the effectiveness and through the parameters of the device selected, the bridge in the role of the earthquake in response to functional requirements expected。(2) in the analysis on the basis of nonlinear, respectively, meet demand is expected to select the function of the different from the shock of the parameter through the structure, nonlinear when the analysis, from the security and economic angle to the reduction of the shock of the parameters for optimization。(3) To bridge the fluid used in dampening and lead a sample of rubber the shock of the basic mechanics of the research. Performance。Through a dynamic process, the analysis and understanding of the structure and members of the horizontal component part of the characteristics and laws passed to the overall structure ; for dampening units terms with the experimental analysis, debug and set reasonable quantity and size reduction of the device to which part of the energy consumption, certain extent reduce the structural members内力level to reduce the structural members, especially the部墩柱and the burden on this basis that the relevant arrangement is designed, Also reduces the lower section of the structure and sinewy. never set up a huge bridge xinhe approach, and take appropriate measures to raise the level of seismic forces to the stump of a foundation, and improve the overall performance. Antiseismic。...
