【摘要】 利用ABAQUS有限元软件,选取温度和长细比为参量,对高温后钢管钢骨混凝土组合柱的轴压稳定承载力进行了模拟研究,得出了温度和长细比对组合柱受压稳定性的影响规律,并推导出高温后钢管钢骨混凝土组合柱的稳定承载力计算公式.更多还原

【Abstract】 Simulation research on the steel tube filled with steel-reinforced concrete subjected to axial compression after high temperature was done by changing the temperature and the slenderness ratio with finite element software ABAQUS.The influence of the temperature and slenderness ratio on the composite column and its stability formula of the composite column after high temperature were gotten by the research.更多还原
