摘要
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。
Taking the under-supported concrete-filled steel tubular arch bridge as the research object, the space finite element analysis module of bridge was established by using finite element, the natural vibration frequency and vibration mode of the bridge structure were calculated. The influences of type, location, and quantity of lateral coupling on dynamic characteristics of the concrete-filled steel tubular arch bridge were quantified.
