摘　　要：钢木组合结构结合了钢材强度高、木材天然可再生这两种建筑材料各自的优点,不仅能够突破以往木结构建筑不能满足的跨度和高度需求,同时也使得钢结构建筑的稳定性和承载力得到极大提高。本文运用ANSYS有限元分析软件建立了钢柱和钢木组合柱的有限元计算模型,同时考虑几何非线性和材料非线性,对钢柱和钢木组合柱的力学性能进行了分析和对比,并从理论上推导了钢木组合柱的设计方法。Steel - timber combined structure combines the advantages of high strength steel and natural renew- able wood. It can not only break through the span and height of the wooden structure building, but also can im- prove the stability and bearing capacity of the steel structure. Using finite element analysis software ANSYS to es- tablish the finite element model of steel column and steel - timber combined column, considering geometric nonlin- earity and material nonlinearity, the mechanical properties of steel column and steel - timber combined column were analyzed and compared, and the design method of steel - timber combined column was deduced.
