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。
Experimental study on two ultimate bearing capacity of single angle steel with local deformation under tension and compression. The results show that the local deformation defects will reduce the ultimate bearing capacity of single angle steel, the larger the deformation, the more the reduction. The local deformation has a great influence on the compressive bearing, but has little effect on the bearing capacity of the bearing. The concave and convex deformation methods have little effect on the bearing capacity.
