| 摘 要： | 利用ABAQUS有限元分析软件建立了配有钢管的SRC柱温度场的有限元分析模型,模拟火灾作用下各个时刻构件的三维温度场分布,并利用试验结果对模型进行了验证,计算结果与实验结果吻合良好。在此基础上,分析了截面周长、型钢含钢率和截面核心面积比对构件温度场的影响规律。研究成果为进一步深入研究配有钢管的SRC柱高温下的力学性能创造了条件。

| Abstract: | The temperature field analysis method of steel tubes reinforced columns under fire is developed using finite element analysis software ABAQUS.The theoretical method is validated by tests,and the calculated results agree well with those of tests.Based on these results,the influencing laws of sectional perimeter,steel reinforcement ratio and core area ratio on temperature field are discussed.These achievements make it possible for further studying the mechanical performance of steel tubes reinforced columns. |
