Analysis And Stabilization Of Continous Rigid Frame Bridge With High Piers And Long Spans

With the rapid development of highways in our country, bridge construction has come in the upsurge period. Beam bridges with high-piers and long-spans are widely used for their advantages, and then have being developed rapidly. So it has the important and realistic significance to make the buckling analysis and present a design that is to satisfy the using function and dependable safety construction and at the same time convenient to construction of the beam bridges consulting to some factors. It offers an experienced instruction to whom will encounter the same circumstance during the practical work in the future.The concrete contents are as follows:1. It discusses nonlinear analysis of the beam bridges with high-piers and introduces the principles of nonlinear analysis of the high-piers using the finite element method.2. In the text, the theory of construction stabilization is generally introduced, the finite-element method is introduced in detail for the stabilization analysis of high piers. The differences of two stability analysis theories and the range of the application in practical engineering are comprehensively considered.3. In the text, it elaborates the basic design principles of the beam bridges with high-piers and long-spans. Based on Jiu jiapeng Bridge, the MIDAS/Civil finite element software by Korea is adopted in this thesis to analyze the structure capability of continuous curved rigid frame bridge with long-span and high-pier (including construction stage and finished stage). The influence of static elastic and geometrical nonlinear behavior on structure is compared. A preliminary nonlinear analysis of continuous rigid frame bridge with long-span and high-pier is also provided in the thesis.
