摘要
钢结构设计规范(GB50017-2003)、门式刚架轻型房屋钢结构技术规程(CECS1022002)关于宽薄腹工形等截面压弯构件的平面内稳定计算,虽然基本原理相同,但具体方法差别甚大。通过对试验数据、由数值法所得的分析结果与按这两种方法的计算结果比较,发现规范的方法在很大范围内偏于保守,且不甚合理;而门规的方法更为经济合理,建议规范也采用门规的方法对宽薄腹工形等截面压弯构件作平面内的稳定计算,使设计更加统一,经济合理。
The in-plane stability design methods for I-section beam columns with slender web used in Chinese codes GBS0017 2003 andCECS 102:2002, though based on the same principle,differ greatly. Comparing the ultimate loads from these two approaches with those from testing and parametric studies by a numerical method, it is found that the method in CECS 102:2002 is more economical and rational than that in GB50017 2003, which is rather conservative for most cases. It is, therefore, suggested that the method in CECS 102; 2002 be also adopted in GB50017-2003.
