在修订《钢结构设计规范》(TJ17-74)中,我们先后译印了1965年至1985年之间的美、英、法、西德、意、奥、挪、加、日、罗、苏等二十几个国家编制和修订的现行钢结构规范、规程和建议。在这些规范、规程、建议中,各国所列入的钢材钢种钢号代号虽然不同,但相应的钢材标准规定的综合性能(包括冶炼工艺、轧制方法、化学成分、机械性能、加工制造等) 差别则不大,作为钢结构设计的强度指标级别也都在同一水平,基本上接近。
In the revised “Code for Design of Steel Structures” (TJ17-74), we have translated and printed the US, UK, France, West Germany, Italy, Austria, Norway, Canada, Japan, Romania, and the Soviet Union between 1965 and 1985. The current steel structure specifications, procedures and recommendations that have been prepared and revised by more than 20 countries. In these specifications, procedures, and recommendations, the steel grade steel grades listed in various countries are not the same, but the comprehensive properties specified in the corresponding steel standards (including the smelting process, rolling method, chemical composition, mechanical properties, processing and manufacturing, etc.) ) The difference is not significant. As the strength indicators of steel structure design are all at the same level, they are basically close.
