多国结构抗火规范关于H型钢柱的比较和分析

介绍了美国、英国、欧洲、澳大利亚和中国的钢结构抗火设计规范中关于受压构件的计算方法,并对它们的区别和联系进行了分析和论述。通过一个算例给出了各国规范的计算结果,并将它们的计算结果进行了对比。研究表明:美国、欧洲和中国规范的钢柱稳定系数差别较大;欧洲、英国和中国规范计算所得的受压构件的临界温度差别很小,澳大利亚规范和美国规范的临界温度偏低;中国规范和欧洲规范的无保护层钢构件耐火时间基本上相同,澳大利亚规范结果偏低,英国规范结果偏高;欧洲和中国规范的有轻质保护层受压钢构件耐火时间基本相同,美国规范耐火时间偏短。...

Abstract 介绍了美国、英国、欧洲、澳大利亚和中国的钢结构抗火设计规范中关于受压构件的计算方法,并对它们的区别和联系进行了分析和论述。通过一个算例给出了各国规范的计算结果,并将它们的计算结果进行了对比。研究表明:美国、欧洲和中国规范的钢柱稳定系数差别较大;欧洲、英国和中国规范计算所得的受压构件的临界温度差别很小,澳大利亚规范和美国规范的临界温度偏低;中国规范和欧洲规范的无保护层钢构件耐火时间基本上相同,澳大利亚规范结果偏低,英国规范结果偏高;欧洲和中国规范的有轻质保护层受压钢构件耐火时间基本相同,美国规范耐火时间偏短。
