摘要
以钢箱梁支点横梁作为研究对象,采用有限元法探讨支点处顶底板横向有效宽度的计算方法,并应用于钢箱梁横梁的简化杆系模型。将板单元模型和杆系模型2种计算结果进行对比,提出宽幅钢箱梁支点横梁合理的简化计算方法。
The calculation method of the fulcrum beam of the steel box girder is studied in this paper.FEA method is utilized to discuss the calculation method of the transverse effective width of the top and bottom flanges at the pivot.Then,this method is utilized to the simplified frame model of the crossbeam of the steel box girder.Compared with the results of the plate element model and frame model,the reasonable and simplified calculation method of the fulcrum beam of the wide-width steel box girder is proposed.
