DISCUSSION ON THE WORKING TEMPERATURE AND QUALITY GRADE OF STEEL MATERIAL
-
摘要: 结构的工作温度是钢结构选材要考虑的一个重要因素。GB500172003《钢结构设计规范》关于这个问题的若干条款显得有些粗糙,甚至有不合理的地方。对此问题进行了探讨,并与美国和欧洲的规范进行了比较,给出的建议可供修改规范参考。Abstract: The structural working temperature is an important factor which shall be considered in selecting steel quality.Provisions in this regard in Code for Design of Steel Structure(GB 500172003) are somewhat rough and even irrational in some instances.Discussion on this topic and comparison with provisions in American and European codes are given in this paper.Suggestions are put forth as reference for forthcoming revision of design code.
