在分析比较中国国家标准《冷弯薄壁型钢结构技术规范(GB50018-2002)》和欧洲标准《Eurocode3(EN 1993-1-3)》的基础上,针对Q345冷弯薄壁卷边槽钢轴压长柱的极限承载力进行了较深入的探讨和对比分析。试验与理论分析表明:按中国国家标准《冷弯薄壁型钢结构技术规范(GB50018-2002)》计算卷边槽钢轴压长柱是可行的,且偏于安全。
Based on the analysis and comparison of the Chinese national standard “GB50018-2002” and the European standard “Eurocode3 (EN 1993-1-3)”, aiming at the cold bending thin-walled steel channel Q345 The ultimate bearing capacity of the long column has been discussed and analyzed in depth. The test and theoretical analysis show that it is feasible and not safe to calculate the curling channel steel axial compression column according to the Chinese national standard “Technical Specification for Cold-formed Thin-walled Steel Structure (GB50018-2002)”.
