白塔大桥截面为多箱单室截面 ,该箱形截面在反对称荷载作用下将产生截面周边变形——畸变效应 ,畸变效应是白塔大桥结构受力分析的一个重要组成部分 ,本文利用箱梁畸变分析的单元刚度矩阵 ,分析白塔大桥在汽车及挂车荷载作用下的畸变效应。
Baita Bridge section is multi-box single-chamber cross-section, the box-shaped cross-section in the anti-symmetrical load will produce deformation around the cross-section effect, the distortion effect of Baita Bridge structural stress analysis is an important part of this paper, Beam Distortion Analysis of Element Stiffness Matrix to Analyze the Distortion Effect of Baita Bridge under the Load of Vehicles and Trailers.
