摘　　要：局部屈曲是组合钢柱常见的失效模式之一.结合某电厂组合钢柱承载坍塌现象,用三维有限元法计算出该组合钢柱的极限荷载,指出了该组合钢柱的破坏机理与破坏过程,并探讨了该类钢柱的局部稳定性问题,提出了解决同类问题的一般性方法.Local buckling is the dominant failure mode for composite steel column. Combining the composite steel column＇s phenomenon of collapsing of a certain power plant, this paper calculates the ultimate load of the composite steel column with the three-dimensional finite element method; points out the fracture behavior and the failure mechanism of the composite steel column; analyses the local buckling of this kind of steel column; and proposes the general method for solving the similar problems.
