加筋板单元是船舶与海洋工程等箱型梁结构的主要组成构件，首先将箱型梁剖面离散成若干加筋板单元和角单元，利用非线性有限元方法逐一计算加筋板单元的应力—应变关系曲线，然后再用逐步破坏分析法得到整个结构的弯矩—曲率曲线，从而求得其极限弯矩。

In the thesis the author analyzes the tripping of stiffened panels by three different methods. Based on the above method, the author calculates the ultimate longitudinal strength of a boxlike girder, several ships and many stiffed panels by program.
