摘要
本文介绍了美国AISI冷弯型钢结构规范关于有效宽度计算的统一法则,并综述了加劲板件、非加劲板件、边缘加劲板件等在各种应力分布状态下的屈曲系数k的计算方法。最后,比较了加劲板件按美国AISI规范和我国规范GB50018有效宽度的计算结果,二者较为接近。
The unified approach for calculating the effective width of cold-formed steel sections,developed in AISI specification,is introduced.The plate buckling coefficient k is discussed for stiffened elements,unstiffened elements and edge stiffened elements with various stress distributions.The calculating results of effective width for stiffened elements by AISI specification are compared with that of Chinese Code GB50018 and the results of two specifications are very close to each other.
