【摘要】 在钢结构的抗火设计中 ,必须了解钢构件截面温度随时间的变化。本文对一侧带有墙板的钢柱在火灾下的升温和截面温度分布进行了有限元分析研究 ,通过数据拟合并对比现有计算方法 ,得到了带墙板钢柱截面平均温度和温度分布的简化方法 ,为进一步进行这种条件下钢柱的抗火设计提供了基础更多还原

【Abstract】 Light wall panels are often used as cladding in steel buildings. Connected with a steel column at the flange of the column,the wall panels will give thermal effect on the column at elevated temperatures and causing an uneven temperature’s distribution in the section of the column.Based on a series of thermal FE simulation and a parametric study,a simplified method for calculating the distribution of temperature in the section of a steel column connected with wall panel is provided.更多还原
