| 摘 要： | 钢管混凝土结构以其优越的力学性能广泛地应用到实际工程中,而将钢管混凝土结构用作桥墩在国内还很少见。目前,对于框架式钢管混凝土结构体系,动力方面的试验研究很少,而理论方面的研究更少,这在一定程度上阻碍了其应用到实际工程中。通过ANSYS软件建立框架式钢管混凝土桥墩模型,并对影响该种类型桥墩的自振频率因素进行分析及初步探索,可为工程实践提供帮助。

| Abstract: | Concrete-filled steel structure is famous by superior mechanical properties, so it is applied in the practical engineering more and more. In China, CFST bridge pier is rarely seen as bridge pier. For CFST structure, the experimental study and theoretical research are less, and these hinder the application to practical engineering in a certain extant. In the paper, a CFST frame bridge pier is established, and the factors affect natural frequency of vibration is studies. Through the preliminary exploration, the authors hope it can be offer help in the realization of actual project. |
