摘　　要：钢结构强度高,构件细长且纤薄,故而构件的稳定问题显得较为突出。很多情况下,钢结构并非由强度控制其构件的选择,因此,合理地选择构件,满足规范规定的宽厚比稳定构造要求,对于钢结构设计尤为重要。对美国规范和中国规范中钢结构抗震局部稳定进行分析和比较,以期对工程设计人员有所帮助。Usually,because of the high strength of steel,the steel member is slender and the steel plate is very thin,the stability design of steel member is very important.In most case,the member selection is not decided by steel strength.How to meet the width-thickness ratio regulation of design code is significant for steel structure design.The local stability of seismic provisions between American Standards and Chinese Standards is analysed and compared which can be benefit to designers.
