摘要
大曲率曲线异形梁桥应用日益广泛,已经成为现代交通工程中的重要桥型。曲线异形桥结构的内力和变形计算趋于复杂。本文利用大型通用有限元分析软件ANSYS,建立了该曲线异形桥的参数化空间实体模型,对该异形桥进行了模态分析,得到了该异形桥的自振频率、阻尼比和振型等动力学参数。
The large-curvature curved Special-shaped Bridge is widely used and has become an important bridge in modern traffic engineering.It is more complicated to analysis internal force and deformation for this type bridge structures.In this paper,the general finite element analysis software ANSYS is used to establish the parametric spatial solid model of the curved shaped bridge.Then the modal analysis is carried out,and the dynamic parameters such as natural vibration frequency,damping ratio and vibration mode of the shaped bridge are obtained.
