摘　　要：对有局部变形的单角钢受拉和受压两种极限承载能力开展试验研究。结果表明:局部变形缺陷会降低单角钢极限承载力,变形越大,降低越多。局部变形对受压承载影响较大,对受拉承载力影响较小;内凹与外凸变形方式对承载力影响不大。The bearing capacity of pulling and compression on single angle steel with local deformation was tested： local deformation could low down the bearing capacity of single angle steel, and low down more with the deformation getting bigger. Local deformation had greater influences on compression bearing capacity than pulling, but the influence of the mode of inside and outside deformation was very small.

关 键 词：局部变形 轴心受力 单角钢
