中外抗震设计规范关于钢柱板件宽厚比限值的比较
|
摘要
板件宽厚比对钢结构的抗震性能有着重要影响,同时也是影响钢结构用钢量的一项重要指标,对钢结构的安全性和经济性均有着很重要的意义.目前国内已有不少文献认为我国现行抗震设计规范对梁柱截面板件宽厚比限值的规定尚不够严谨和完善,并对此提出了设计建议.结合中国抗震规范GB50011—2001、美国钢结构抗震规范ANSI/AISC 341—05、日本抗震规范BCJ和欧洲抗震规范Eurocode 8的相关规定,比较研究了中外抗震设计规范对工形截面和箱形截面钢柱板件宽厚比限值规定的异同,分析了中国抗震规范GB50011—2001关于钢柱板件宽厚比限值的合理性,为相关设计和研究提供了参考.
The limiting width-thickness ratio plays an important role in steel structures' safety and economy,as it not only has a significant influence on steel structures' seismic performance,but also is an important index of steel consumption for steel structures.At present,many domestic research results show that the limiting width-thickness ratios in our country's seismic design code are not adequate or reasonable and have presented corresponding design recommendation.The limiting width-thickness ratios in the related Chinese code GB50011—2001,American code ANSI/AISC 341—05,Japanese code BCJ and European code Eurocode 8 are compared and analyzed,which provides a reference for the relevant steel structure design and research.
