摘要
利用大型通用有限元程序建立了某中承式钢管混凝土拱桥的三维空间有限元模型,计算了该桥梁结构的自振频率和振型,计算结果可为该桥的设计、施工以及使用阶段的健康检测和维护提供技术参数和依据。
Three dimentional space finite element model for a half- through arch br/dge 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.
