摘要
基于大型空间有限元程序Ansys10.0,利用箱梁分析常用荷载分解法,对薄壁钢箱梁在偏心荷载作用下不同数量横隔板的设置对薄壁钢箱梁畸变效应的影响加以分析,并重点考察畸变效应下薄壁钢箱梁的横向畸变位移、畸变挠度、纵向翘曲位移以及翘曲正应力的分布情况,可得到横隔板设置的密度对薄壁钢箱梁畸变效应影响曲线图。
Based on large-scale finite element program-AnsyslO.O, analyzing the influence of the distortion of thin-wall steel box girder by different amount of transverse diaphragm with common load decomposition, and emphasizing on the distribution of distortion displacement, distortion flexibility, vertical warp displacement and warp stress on the distortion of thin-wall steel box girder, it can draw the curve of the transverse diaphragm design density on distortion of thin-wall steel box girder.
