摘　　要：为了研究钢牛腿柱这种特殊结构构件在偏心压力作用下的受力特性,文中基于工程力学将牛腿柱视为悬臂柱进行理论分析,得出牛腿柱结构应力的解析解。利用有限元软件ABAQUS建立三种牛腿柱的三维有限元模型,进行偏压荷载作用下静力分析,得到牛腿柱的应力分布。结果表明改变加载位置会对结构的应力状态产生较大影响,找出合理的加载位置可以使得构件更好地发挥受力性能。最后给出此工程单牛腿柱合理加载位置和构造措施建议,为同类工程提供参考。To study the stress characteristics of steel corbel column under eccentric pressure,the corbel column is regarded as a cantilever column for theoretical analysis based on engineering mechanics.The three-dimensional finite element models of three kinds of corbels are established by using ABAQUS software,and the analytical solution of structural stress of corbel column is obtained.Furthermore,the static analysis under eccentric load is carried out,and the stress distribution of corbel columns is obtained.The results show that changing the loading position would have a great impact on the stress state of the structure,and finding out the reasonable loading position can make the component better exert its mechanical performance.Finally,the reasonable loading position and structural measures of the single corbel column in this project are proposed,which may provide reference for similar projects.
