| Abstract: | Three dimentional space finite element model for a half-through arch bridge of steelpiped concrete has been established by current finite element program in large-scale for calculating the autooscillation frequency and the autooscillation type.Calculated results would offer technical parameters and basises for design,construction,health detection and safeguarding a service stage of present bridge. |
