| 摘 要： | 基于空间有限元法,以株洲建宁大桥斜拉桥为工程背景,分别建立了斜拉桥成桥状态设置结构横坡和未设置结构横坡的有限元模型,通过计算结果的分析和比较,论证了结构横坡对斜拉桥箱梁剪力滞效应的影响,指出在研究斜拉桥箱梁顶板剪力滞效应时不能忽略横坡的影响.

| Abstract: | On the background of Jianning bridge in Zhuzhou,this paper studied the influence of cross slope on the shear lag based on the spatial finite method.After established two finite elementary models in which cross slope may be considered or ignored,some conclusions are obtained based on analyzing and comparing the calculated results.Finally this paper points out the influence of cross slope can not be ignored while studying the shear lag effect of box girder top flange in the cable-stayed bridge. |
