| Abstract: |
This paper aims to explore the challenge of the design of over one-kilometer-long span road-rail cable-stayed bridge. Because of the large live load and the weight of the structure itself, it has important theoretical significance and engineering application value to study the design parameters of the long Road-Rail cable-stayed bridge with a main span of over 1000 m. The main content of this paper is to study the Steel Road-Rail Cable-stayed Bridge with a main span of 1200 m. The finite element model is established by large-scale analysis software to calculate the response of the structure under load. Based on the calculation results, the rationality of long-span cable-stayed bridge are preliminarily researched. Wind and seismic loads are not considered. |
