摘　　要：介绍了工程中两类用于计算下船体隔框加筋结构压缩许用载荷的算法,结合与其结构相似的加筋壁板压缩试验进行了分析,表明约翰逊—欧拉算法更适用于该部位的压缩稳定性计算。In this paper, the accuracy and applicability of two methods which were used to calculate the compression allowable value of frame＇s stiffened panel were analyzed, through combining the stability test of the stiffened panels. The results show that Johnson-Euler equation is more appropriate for calculating the compression stability of the frame＇s stiffened panel.
