摘要
尝试将我国GB 50018-2002《冷弯薄壁型钢结构技术规范》用于计算屈服强度不是Q235和Q345的钢材制成的冷弯薄壁型钢梁,并将我国规范计算结果与试验结果、国外规范计算结果相比较。对于发生局部屈曲的梁,我国规范计算结果安全;结果表明:对于发生畸变屈曲的梁,我国规范计算结果不安全。
The cold-formed thin-walled steel beams whose yield strengths are not Q235 or Q345 are calculated with Chinese code GB 50018-2002 in this paper.As compared with the results of a series of tests and other standards abroad,the predictions of Chinese code are safe for the beams failed by local buckling and not safe for the beams failed by distortional buckling.
