摘要
采用MIDAS/Gen分析软件,对冷弯薄壁型钢-泡沫混凝土组合结构进行屈曲特征值和承载力分析,研究结构在自重和一定的均布荷载作用下的应力分布、位移-荷载系数关系和各向位移情况。结果显示:结构几何初始缺陷对结构承载力影响不大;增加C型钢厚度可以减小结构侧向位移和结构主应力,有效提高结构承载能力。
Through the MIDAS/Gen analysis software, the buckling eigenvalues and bearing capacity of cold-formed thin-wall steel and foam concrete composite structure were studied, and the load coefficient and the displacement of stress distribution under the load of self-weight and certain uniformly distributed load were researched. The result showed that the structure geometry initial defect has little influence on the bearing capacity of the structure; increasing the thickness of C steel can reduce the lateral displacement and structural principal stress, and effectively improve the bearing capacity of the structure.
