“碗形”箱梁断面梁格法分析计算

近些年来,随着城市化进程的加快,我国越来越多的城市都新建了城市高架系统,另一方面,对于宽幅、异形断面箱梁,普通的单梁计算模型已经很难讲清楚主梁的受力模式,为此须建立空间模型加以验证。利用空间梁格模型对近年来常用的“碗形”断面连续箱梁进行了分析计算。

Analysis of Bowl-like Girder Using Grid Method

Recent years, as urbanization speeding up, more and more cities have been construc- ting their city-elevation-system, on the other side, single beam modal can＇ t reflect the pattern how the structures take the force, so we must set up space modal to verify what we have got from single boam mo- dal. Using grid method, this article analyses the bowl-like girder.
