摘要
《油船共同规范》引入加筋板极限强度的概念,能够更加真实评估加筋板的承载能力,从而推动了现代船舶结构设计技术的进一步发展.加筋板结构极限强度研究的内容颇多,通过计算侧压+单轴压缩、侧压+双轴压缩工况下加筋板的极限强度,探讨侧压对加筋板极限强度的影响.分析了侧压对加筋板极限强度的利弊,对比相同侧压作用下单轴受压加筋板和双轴受压加筋板极限强度下降程度.
The concept of ＂ ultimate strength＂ was introduced by Common Structural Rules for double hull oil tanks which could be more realistic to access the ultimate bearing capacity of stiffen plates that can promote the modern ships technology.Regards to ultimate strength,a lot of researches have done on it,and this paper focus on investigating the effect of lateral pressure on the ultimate strength of stiffen plates by calculating the ultimate strength of stiffen plates under lateral pressure＋axial compression and lateral pressure＋double axial compression.The advantage or disadvantage influence of lateral pressure on the ultimate strength of the stiffen plates are analyzed.In addition,the degree of ultimate strength of the stiffen plates under lateral pressure＋axial compression with it under lateral pressure＋double axial compression is compared.
