以下承式钢管混凝土拱桥为研究对象,采用有限元建立了桥梁的空间有限元分析模型,计算了该桥结构的自振频率和振型。量化了横向联结类型、数量、位置对钢管混凝土拱桥动力特性的影响规律。
The following CFST arch bridge is taken as the research object. The finite element model of the bridge is established by finite element method, and the natural frequency and mode shape of the bridge are calculated. The influence of the type, number and location of transverse connection on the dynamic characteristics of CFST arch bridge was quantified.
