摘　　要：为验证和完善船体结构极限强度非线性有限元法,采用高强度钢,设计典型箱型梁4点弯曲模型,开展极限强度模型试验,得到典型箱型梁模型的极限承载力和应力分布情况,与模型试验数值仿真的结果对比,结果吻合,可为船体结构极限强度计算方法研究提供试验支撑。In order to verify the accuracy of nonlinear finite element method for the ultimate strength of ship structures,a four-point bending model of typical box-girder using high strength steel was designed. Through the model test research on ultimate strength of typical box-girder,the ultimate bending capacity and stress distribution were obtained,and it is good agreement with the nonlinear numerical simulation result. It can provide an experimental support for the research of ultimate strength calculation method of hull structure.
