| 摘 要： | 在分析曲线箱梁桥剪滞效应时,使用多参数翘曲位移函数,并考虑了轴力平衡条件;在流动的圆柱极坐标系下,建立了包含剪滞效应的每节点有１０个自由度的薄壁曲线箱梁一维有限元列式。分析结果与文献（１,２）中的结果比较表明：该方法是简捷而有效的。

| Abstract: | One dimensional finite element formulea
for thin-walled curved box girder analysis including the shear lag effect are presented
under convected cylinder coordinates.The results obtained from this paper compared with
these from other references ［1,2］ show that the method presented by the author is simple and
effective. |
