【摘要】 利用空间有限元法分析芜湖长江大桥公路钢筋混凝土桥面板由于剪力滞后效应导致的桥面板的有效宽度，与常规计算方法相比避免了把钢桁架近似等效为薄壁箱梁和求解微分方程，解的精度比较高：最后给出了桥面板的有效宽度，以便能为设计提供一些帮助。更多还原

【Abstract】 In this paper,the spatial finite element method was introduced into the analysis of Wuhu Changjiang River Bridge deck’s effective width.By contrast with the conventional way,the steel truss equivalent to the thin walled box girder and the solution of differential equation were avoided,and the precision solution is high.The effective width of deck was given,so it could provide some help for the designing.更多还原
