| 摘 要： | 通过理论分析提出了冷弯薄壁型钢—混凝土组合梁钢梁腹板及翼缘的局部屈曲简化计算模型。继而在简化计算模型的基础上应用能量法分别求出了腹板及翼缘的弹性临界屈曲应力。结果表明,内填混凝土的存在有效地提高了腹板及翼缘的屈曲应力,改善了腹板及翼缘的局部屈曲性能。

| Abstract: | A model is presented for analyzing the local buckling property of cold-formed thin-wall steel-concrete composite beam.And the elastic buckling stresses of steel beam web and flange wall are calculated by the energy method.It's found from the analysis that the elastic buckling stresses of steel beam web and flange are enhanced because of the concrete inside the composite beam.The local buckling property of the composite beam is improved obviously. |
