Abstract:The limit span of self-anchored cable-stayed suspension bridge is deduced. The relations among the geometrical parameters, the loads and the material characteristics are also analyzed. Based on the material strength and the commonly used materials, the limit spans of self-anchored cable-stayed suspension bridges with concrete girder or steel girder under vertical static load are discussed in detail. The corresponding upper limit spans and the influence of the factors on the span are given. The results indicate that increasing rise-span ratio, height-span ratio, cable-stayed segment length or reducing the second dead load can increase the cooperation system span.
