| 摘 要： | 梁宽较大的斜拉桥钢箱梁在自重和二期恒载的作用下,在横桥向有着较大的挠度,在设计中必须予以考虑。文章应用Ansys结构计算通用程序中结构分析模块,对钢箱梁就影响横向挠度的多种变量分别进行了计算,并对计算结果进行对比分析,找出了影响该量值的主要因素,以及各变量对钢箱梁横向挠度的影响程度,为以后的设计提供了数值依据。

| Abstract: | Under the dead weight and the secondary dead load,the steel box beam of the wide cable-stayed bridge has a large deflection in the transverse direction,which can not be neglected in the bridge design. In this paper,the structural analysis module of Ansys software is used to calculate the transverse deflection of the steel box beam in terms of multiple factors and the results are compared and analyzed. The main factor influencing the transverse deflection is found out,and the action degrees of the multiple factors influencing the deflection are given, which can be a numerical basis of the (design.) |
