摘　　要：为研究钢木组合柱的轴压性能,设计了一种T形钢木组合柱。对一个纯钢柱和三个钢木组合柱进行轴压试验,分析极限荷载和延性系数,并将破坏形态与有限元模拟结果进行对比。结果表明:螺栓孔洞对纯钢柱的承载力有一定的削弱作用;木板对纯钢柱提供了侧向约束,能有效提高纯钢柱的承载力,随着木板厚度的增加,钢木组合柱的承载力增大;构件破坏时,有限元模拟得到的加劲肋弯曲位置、弯曲程度与试验基本一致。In order to study the axial compression performance of steel-wood composite columns,a t-shaped steel-wood composite column was designed.Axial compression tests were carried out on one pure steel column and three steel-wood composite columns to analyze the ultimate load and ductility coefficient.The results show that the bearing capacity of pure steel column is weakened by Bolt Holes,and the bearing capacity of pure steel column is increased with the increase of the thickness of wood.When the member is damaged,the bending position and degree of the stiffener obtained by finite element simulation are basically consistent with the experiment.
