摘　　要：极限强度是结构的极限承载能力,由于计算极限强度需要考虑材料和几何的非线性因素,因此计算十分复杂.文中介绍了M sc/M arc所采用的两种计算非线性屈曲方法的计算原理,并分别运用这两种方法对N sh ihara N ST 3模型进行了非线性屈曲分析,最后将计算结果和其他计算极限强度算法的结果作了简单比较,得到的结果对类似的分析有一定的指导意义.Ultimate strength is the ultimate bearing capacity of structure. Considering material and geometrical nonlinear factors, calculation will be very complex. The calculation principle of two kinds of methods is introduced for calculating nonlinear buckling in the Msc/Marc. Nonlinear buckling analysis is made for Nshihara NST3 model by Msc/Marc. Making simple comparison between the analysis result and the ones by use of other ultimate strength calculations, from which conclusions gained, is helpful for similar analysis.
