摘要 在计算框架的稳定性时,需首先确定柱子的计算长度l0,该计算长度l0由计算长度系数μ确定。中国《钢结构设计规范》(GB50017-2003))与美国钢结构规范《AISC-Load and Resistance Factor Design Specification for Structural Steel Buildings》在确定柱子的计算长度系数μ时存在一定的差异,对两者的基本假定、计算公式和修正系数进行比较。 In the computation of frame stability, the effective length of frame columns is determined by the effective length coefficient. There are differences in determining the effective length coefficient of the pillar between "The Code for Design of Steel Structure" (GB 50017-2003) and the American steel structure specification "AISC- Load and Resistance Factor Design Specification for Structural Steel Buildings". It compares the basic hypothesis, formula and correction coefficient between the two design standards.
