In this thesis, structural spatial behavior of concrete truiss suspension brdge is studied.Through repeatedly debugging, an accurate method is found to create and solve acompleted three-dimensional finite element model of the XiaYang suspension bridge byusing the ANSYS/ED5.4 software. Through static analysis, model analysis and parametricstudy, and comparing with the result of on-site dynamic test, it is found that the concretetruss suspension bridge still has the fethee of flexible stfucture and the initial tension in thecab1es has a significant influence on the suspension bridge. The concrete truss suspensionbridge can reduce disease to increase economic and social benefit by adjusting the initialtension and strengthening in some place.
