摘要
研究横隔板间距对悬挑箱梁畸变的影响 .通过设置不同数量横隔板的悬挑箱梁在均布扭矩作用下 ,比较畸变效应和刚性扭转效应 ,得到最大畸变效应随横隔板密度的变化曲线 .当横隔板间距 d与截面最大尺寸 b的比值大于 0 .5 35 7时 ,闭口截面杆件的约束扭转分析应考虑畸变的影响 ,尤其对于高层核心筒结构 .
The influence of the spacing of diaphragm plates on the distortion of cantilever box giredr is studied. By comparing distortion effect and rigid torsion effect of cantilever box girders installing with diaphragm plates in different number under the action of torque evenly spread, the authors obtain a curve showing that maximal distortion changes with diaphraqm density. Thus a suggestion can be advanced as follows: when the ratio of diaphragm spacing d to the maximal dimension of cross section b is greater than 0.535 7, the effect of distortion has to be considered in analysing restraining torsion of the member with closed cross section. This is a suggestion of guiding significance to the practical engcneering, esp, high rise core tube structure.
