摘要： 对18 根板件中间加劲复杂卷边槽钢简支轴心受压试件进行了承载力试验研究，其中包括有截面形式、试件长度等方面的变化，研究了板件中间加劲对构件承载能力和破坏模式等方面的影响.试验结果表明: 板件帽形加劲可以大大提高构件的稳定承载力.与普通复杂卷边槽钢构件相比，在相同条件下采用板件帽形加劲的构件其承载效率提高了大约10%~40%，其破坏模式变为以畸变屈曲为主要控制因素的畸变及其相关屈曲的破坏.同时利用有限元软件模拟相同试件的承载力和破坏模式，与试验结果吻合良好.

Abstract: A total of 18 simply supported axial compression members with three types of complicated sections were tested. The bearing capacity， buckling mode and deformation behavior of these members were studied. The results show that cap shaped stiffeners can increase the ultimate load-carrying capacity of loaded members obviously. Compared with channels with complex edge stiffeners under the same condition， members with cap shaped stiffeners can make the ultimate load-carrying capacity be increased about 10% to 40%. Distortional and local interaction buckling became the main buckling modes. Numerical simulations were performed by finite element analysis. The analysis results are in good agreement with experimental data.

Key words: channel with complex edge stiffeners, element with cap shaped stiffeners, static test, load-carrying capacity, buckling mode
