An Analysis of Stable Bearing Capacity of Long Span Steel Tubular Concrete Arch Bridge |
| |
| Abstract: | A discussion was presented of elastic stability and ultimate bearing capacity of long span steel tubular concrete arch bridge during construction and operation. In analysis and computation, the impact of the following factors was taken into consideration: rigidity variation of bridge structure at different stages; successive formation of section; and ultimate bearing capacity of structural members. |
