摘要
利用大型通用有限元程序建立了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。
The half-through concrete filled steel tublar arch bridge＇s three-dimensional finite element model is established and the natural frequency and modes are calculated through the application of the finite element analysis software. The calculating results can offer the related technical parameters and basic data for the design certification, construction, health detection and maintenance in working conditions.
