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。
The combination of steel and wood combines the advantages of high strength of steel and natural regenerability of wood, which not only can not meet the span and height requirements that can not be met in the past, but also makes the stability and bearing capacity of steel structure Get greatly improved. In this paper, ANSYS finite element analysis software was used to establish the finite element model of steel column and steel-wood composite column. The mechanical properties of steel column and steel-wood composite column were analyzed and compared considering geometric nonlinearity and material nonlinearity The design method of steel and wood composite column is theoretically deduced.
