摘要
以三汊矶自锚式悬索桥工程为例,利用通用有限元分析软件ANSYS建立大桥的动力模型,计算了前16阶频率及振型,并具体分析了恒载、加劲梁刚度、桥塔刚度等结构参数,提出了自锚式悬索桥动力特性的影响规律。
Taking one self-anchored suspension bridge as example utilizing finite element analysis software-ANSYS dynamic model of this bridge is built. First 16 frequencies and modes are calculated. In addition, dead load, rigidity of stiff girder, rigidity of bridge tower and other structetral parameters are analyzed. In the end factors influencing the dynamic characteristics of self-anchored suspension bridge are summarized.
