摘要:Geometrical nonlinearity of self-anchored cable-stayed suspension bridge was studied. The influences of shrinkage and creep of concrete, rise span ratio and girder camber on system were discussed. A self-anchored cable-stayed suspension bridge with main span of 800 m was analyzed with linear theory, two-order linear theory and nonlinear theory. The moment and displacement of girder, pylon under different rise span ratio and girder camber stages with live load were gotten. According to the results of analyses, the live load of a self-anchored cable-stayed suspension bridge with main span of 800 m can be analyzed with two-order linear theory and the error is less than 6%.The shrinkage and creep of concrete greatly affect the structure. And the system stiffness is superior to that of suspension bridge. As the rise span ratio becomes larger, the axial force and stiffness of main cable and girder are smaller. The system stiffness increases if main girder camber is set.
