采用梁格法对一个结构较为复杂的异型箱梁建立空间有限元模型进行了分析计算,通过计算分析研究表明:用梁格法来分析桥梁上部结构,能得到比较准确的计算结果,在工程设计中是一种比较简便、高效、实用的计算方法。
The finite element model of a box girder with more complicated structure is analyzed and calculated by using the beam method. The results of calculation and analysis show that using the beam grid method to analyze the superstructure of the bridge can get more accurate calculation results, which is a kind of engineering design More simple, efficient and practical method of calculation.
