船舶破损属于危险状态，快速准确地校核破损船舶结构强度对于应急救援等工作有着重要意义。以某散货船破损工况为例，分别采用等值梁法与有限元法评估破损船舶的结构强度。计算表明，传统的等值梁法未能真实反映船舶破损后的变形及横向构件的应力，具有一定的局限性，有限元法则弥补了此项不足，该方法可为今后船舶破损的计算分析提供参考。

Damaged ship would be in a dangerous state. Fast and accurately by checking the strength of damaged ship structure has important significance for emergency response. Under typical damaged conditions, strength of ship structure is calculated with theoretical simple beam method and finite element method (FEM) respectively. It is found that the traditional simple beam method has some limitations such as failing to express real deformation of damaged ship and stress of transverse member, but FEM makes up for these deficiencies. The proposed method may provide reference for real damage estimation in future.
