大纵肋正交异性钢—RPC组合桥面板有效宽度分析

Analysis of effective width of composite longitudinal rift orthotropic Steel-RPC deck plate

应用ANSYS进行有限元模型的建立,对大纵肋正交异性钢—RPC组合桥面板翼板的有效宽度影响因素进行分析,研究各个因素对其有效宽度的影响规律。结果表明:宽跨比、荷载类型、沿跨方向对其有效宽度的影响比较大。

In this paper,ANSYS is used to establish the finite element model,and the factors affecting the effective width of the large longitudinal rib orthotropic Steel-RPC composite deck flanges are analyzed to study the influence of each factor on its effective width. It was found that the width-span ratio,the type of load,and its effective width along the span direction are relatively large.
