| 摘 要： | 利用有限元分析软件Ansys,采用荷载分解方法将作用于箱梁的偏心荷载进行分解,得到箱型组合梁在偏心荷载作用下设置不同数量的横隔板对畸变效应的影响。重点考察了箱型组合梁的横向畸变变形、竖向畸变变形、纵向翘曲变形的分布情况,得出了横隔板设置数量对畸变效应的影响。

| Abstract: | Finite-element analysis software Ansys is utilized,load decomposition method is adopted to decompose the eccentric load on box beams,and the effect of setting a different number of diaphragms under the action of eccentric load on the distortion effect of box composite beams is obtained.The distribution of horizontal distortion,vertical distortion,and longitudinal buckling deformation of box composite beams are focused on and the effect of set number of diaphragms on distortion effect is obtained. |
