摘要：

The current paper presents an experimental investigation on local-overall buckling behavior of extruded 6063-T5 I-shaped aluminium alloy beams. 3 specimens with different slenderness ratio and different width-to-thickness ratio of plate elements were tested subjected to patch loading. Failure modes, peak loads, load-defbrmation responses and load-strain curves of the beams have been focused on and the results has been compared with code of GB 50429-2007. Two of the specimens occurred typical local-overall buckling, however, the lateral deformation of the other one was not obvious. The comparison indicated that the Chinese standard is too conservative. A finite element model is developed and verified by the tests. With the validated FE model, a parametric analysis of 99 simulations with a large range of slenderness ratio and width-to-thickness ratio of plate elements is presented. And it is found that when the ratio of lambda(y)/(H-w/T-w) is in the range of 1.94 similar to 3.56, local-overall buckling is most likely to occur.
