| 摘 要： | 为研究三面火灾作用下方钢管混凝土柱抗火性能,分析了三面受火的方钢管混凝土柱截面温度分布,并与以往试验结果进行对比,理论分析结果与试验结果吻合良好.在此基础上,对三面火灾和四面火灾作用下方钢管混凝土柱截面温度分布形式进行对比,分析了升温时间、截面边长、含钢率、保护层类型及厚度的影响规律.分析结果表明,升温时间、截面边长、保护层类型及厚度是三面火灾作用下方钢管混凝土柱截面温度场的主要影响参数.

| Abstract: | To study the fire resistance behaviour of concrete-filled steel tubes(CFST) under three-side fire,a finite element model predicting the cross-sectional temperature distribution of CFST is developed using ANSYS.The predicted temperature distribution is in good agreement with the test results.Furthermore,comparisons are made between the temperature distribution of columns heated on three sides and four sides.Based on the FE model,a developed parametric analysis is undertaken,in which time,cross-sectional dime... |
