折线形钢箱柱受力性能试验研究
Experimental research on load-carrying behavior of zigzag welded box column
摘要
Abstract
In order to investigate the mechanical performance of zigzag welded box columns, a scaled model test and FEA were carried out to validate the design and the ultimate bearing capacity.Experimental results show that the test specimen under the design loads is in elastic state.In the ultimate bearing capacity test, the failure mode of the column is that local buckling occurred in the inner corner of specimen which led to great deformation and the lost of load-carrying capacity.According to the results of the test and the FEA, the force distribution, deformation characteristics and ultimate bearing capacity of the specimens were analyzed.The analysis shows that the experimental results match well with the finite element analysis results.The test results demonstrate the correctness and reliability of the theoretical analysis and the original model of structural design.关键词
