摘要:
对 L220X20 的 Q420 角钢进行了轴心受压试验研究,在此基础上进行了理论分析.结合有限元,对大规格角钢进行 了参数分析,并与现行《钢结构设计规范》中给出的柱子曲线进行了比较.结果表明:大规格高强等边角钢柱子曲线高于现有《钢结构设计规范》中b 类截面柱子曲线,总体介于a类与b 类截面柱子曲线之间,现有规范b 类柱子曲线适用于大规格高强等边角钢.
Abstract:
The Q420 angle of L220X20 axial compression test is carried out, and make a theoretical analysis is made on this basis. Combined with the finite element, analysis is made on the angle of the large size parameters, which is compared with the columns curve of the current steel design code. The results showed that: the columns curve of the large-size high-strength edge angle is higher than the current “design code of steel structures” class section column curve, in general between a class between the curve and b-type cross-section columns. The b-class columns curve of current “design code of steel structures” can apply to the high-strength side angle.
