The Design And Research On The East Bridge Of ZhuangHe Construction Street

Self-anchored suspension bridge type is very competitive in the Small and Medium Bridges. Zhuanghe City, the construction of Main Street East Bridge is the one in the span of200meters of concrete self-anchored suspension. This article in order to bridge engineering background, the use of specialized finite element software of MIDAS CIVIL finite element model of the space of the full-bridge, full bridge analysis and design. The main content is as follows:(1) Taking the project as the background, has established the entire bridge spatial finite element model. Analyzes the three main cable form calculation method, on the basis of preliminary calculation bridge cable to form and the results are analyzed and compared, by comparing the three methods to choose the suitable method to the cable bridge form accurately the analysis.(2) Through the MIDAS CIVIL has established the entire bridge space finite element model, analyses the structure in the constant load of the main cables, the boom, girders, tower bridge force; The analysis on the structure including the on-board and temperature effect in under the influence of the main components of bridge; Consider of concrete material shrinkage and creep of the nonlinear effect function, analyzed the structure in the time of the nonlinear effect under the influence.(3) Through the establishment of the structural dynamic analysis of finite element model, calculated by the self-anchored suspension bridge natural frequencies and mode shapes, and dead loads, the bridge towers and stiffening girder stiffness parameters on the vibration characteristics...
