摘要
针对二维梁格模型在箱梁空间分析中不能准确计算横向弯曲及扭转变形的缺陷,提出顶、底板及腹板分别建模的分层式梁格模型,并对一简支双室箱梁进行了静、动力分析,考察了该模型的有效性,为抗震分析奠定了基础。
In light of the defect of 2D beam grid model which can not accurately calculate lateral bend and torsion deformation in box-girder space analysis, the article puts forward stratified beam grid model separately molding on ceiling, base plate and belly plate, carries out static and dynamic analysis of a simply-supported box-girder with double room, examines the effectiveness of the model, in order to lay the foundation for seismic analysis.
