| 摘 要： | 以某大跨度中承式钢管混凝土拱桥为例,基于ANSYS软件建立了该桥的三维有限元模型,研究了考虑桩-土-结构相互作用对大跨度钢管混凝土拱桥风振响应的影响.结果表明:考虑桩-土-结构相互作用后,结构的自振频率减少,风振响应有所增加.

| Abstract: | Taking a long-span concrete-filled steel tube arch bridge as an example,based on the software ANSYS,the spatial finite element models for the bridge were build.The effects of pile-soil-structure interaction（PSSI） on the long-span concrete-filled steel tube arch bridge to wind-induced vibration were also studied.Results show that the Natural frequency of the structure considering PSSI may be smaller than that of the structure without considering PSSI,and the wind-induced vibration response may also increase. |
