摘要
考虑钢管初应力的影响,采用通用有限元分析软件对方钢管混凝土轴心受压构件进行了受力全过程的分析,并以此为基础,分析了不同钢管初应力系数对钢管混凝土构件轴压工作性能的影响,为其进一步的研究提供了基础。
By considering the effect of initial imperfection, finite element software is used to perform nonlinear finite element analysis of behavior of square concrete-finned steel tubes under axial compression. Based on the theoretical model, the effects of imperfection under different initial stress on the behavior of composite columns are analyzed, offers theoretical foundation for further research.
