摘　　要：与ALC墙板相连的高频焊接H型钢柱与单纯钢柱的抗火承载力将会有所差别,文章通过有限元分析,研究了墙板对火灾下钢柱的抗火承载力影响和钢柱在火灾下的特性;将有限元分析结果与规程计算结果进行比较,验证了有限元分析的可靠性,并在此基础上分析了荷载比和截面温度梯度,为带墙板的钢柱抗火设计提供依据。The fire-resistant bearing capacity of high-frequency welded H steel column with ATC wall board attached is different from that of pure steel column.Through the finite element analysis,the effect of wall board on the fire-resistant bearing capacity of steel column in fire is studied as well as the properties of steel column in fire.The results of the finite element analysis are compared with those of the calculation according to related standard,which validates the reliability of the finite element analysis.The relevant parameters are also analyzed including bearing ratio and section temperature gradient.The study can promote the fire-resistant design of steel column with wall board.
