Experimental study on load-carrying behavior for joints of zigzag welded box column
摘要
Abstract
An experimental program and associated FEA were carried out on 1∶3 scale joints models of zigzag welded box columns.The experimental program included the test under the most unfavorable load combination and the ultimate bearing capacity test.The experimental results show that the joint is in the state of elasticity under designed loads.In the ultimate bearing capacity test, the most unfavourable working position of the joint is the zone where the horizontal segment intersected the lower segment, with stress concentration appeared at the inner comer of the zone, however, there is no obvious local buckling.The analysis shows that the experimental results match well with the finite element analysis results, demonstrating that both theoretical analysis and original structure design are reasonable.The study reveals that the joint of zigzag welded box column which has reasonable configuration and excellent weld quality, can be used in load-bearing structures.关键词
