摘要
在对以往钢管混凝土柱耐火极限影响因素系统研究的基础上 ,提出了按规范ISO -834或GB9978-88规定的标准升温曲线升温作用下钢管混凝土柱防火保护层厚度的实用计算方法 ,计算结果与数值计算和试验结果均吻合较好 ,且略偏于安全。
Based on the analysis of the parameters that influence the fire resistance of concrete filled steel pipe columns,formulas for the calculation of fire spray materials thickness of the composite columns under ISO 834 or GB9978 88 standard heating up curve are presented in this paper Generally,the calculated results show good agreements with the numerical and experimental results,and tend to safety The formulas presented in this paper may be referenced for the practical design and code writing
