摘要
采用通用有限元程序ANSYS建立了天兴洲大桥的动力有限元模型,在忽略桥梁非线性因素的情况下,建立了流体阻尼器对天兴洲大桥的纵向地震反应控制方程。采用流体阻尼器对天兴洲大桥纵向地震反应的控制进行了仿真分析,并对流体阻尼器粘滞阻尼系数对控制效果进行了分析,得出了流体阻尼器能够有效抑制天兴洲大桥的纵向地震反应的结论。
The dynamic finite dement model of Tian Xingzhou Bridge was established by general FEM software ANSYS. The longitudinal motion equation of Tian Xingzhou Bridge with fluid dampers was established under the seismic excited, which ignored the influence of non-linear response of cable-stayed bridge. The relationship between viscous damper coefficient of fluid dampers and control effect was analyzed. Numerical simulation showed that fluid dampers could effectively suppress the longitudinal seismic response of Tian Xingzhou Bridge.
