摘　　要：基于ABAQUS有限元软件建立了温度场和力学性能分析模型,将模拟结果与试验结果进行比对,验证了模型的可靠性。在此基础上建立了钢管混凝土短柱在高温火灾下的均匀受火和三面受火轴压的温度场模型,探讨了截面尺寸、钢管强度、混凝土强度、受火方式等因素与高温(受火)下钢管混凝土短柱的力学性能之间的关系。Based on ABAQUS finite element software,an analysis model of temperature field and mechanical properties was established.The reliability of the model was verified by comparing the simulation results with the test results.On this basis,the temperature field models of uniform fire and axial fire compression on three sides of CFST short columns under high temperature fire are established,and the relationship between section size,steel tube strength,concrete strength,fire mode and mechanical properties of CFST short columns under high temperature(fire)is discussed.
