自锚式悬索桥的非线性分析

s the demand of the urban construction changes and the further development of science and technology, the self-anchor suspension bridges gained development and considerable attention in recent years. At home and abroad have a lot of the self-anchor suspension bridge has been built and put into use, there are more and more self-anchor suspension bridge is under planning design and construction. The analysis method, the related theory of self-anchor suspension bridge and the self-anchor suspension bridge construction technology still exist many problems, it remains to be further studied and solved. This paper analyzes the space since the anchor static nonlinear analysis theory and method of suspension bridges, mainly adopts the Midas software analyzed the self-anchored suspension bridge under the action of the vertical load, considering the influence of geometric nonlinear, getting the corresponding results of the analysis, and discussed the result.
