摘　　要：论文以某结构框架—剪力墙井塔结构为模型,对该结构标高18.2m处进行抽柱处理,并将转换大梁设计为型钢混凝土转换梁。利用有限元软件对大跨度型钢混凝土转换梁受力性能进行了竖向荷载下的受力分析,发现在改变型钢腹板厚度时,不断增大型钢腹板厚度并不能持续增强转换梁的承载能力。The paper takes a structural frame-shear wall well tower structure as the model, and draws the column at 18.2m elevation, and designs the converted girders into steel-concrete conversion beams. The finite element software is used to analyze the mechanical behavior of long-span steel-concrete conversion beam under vertical load. It is found that increasing the thickness of the steel web can not continuously enhance the bearing capacity of the conversion beam when changing the thickness of the steel web.
