船體下垂
英文

This thesis used along caldwell ' s direct calculation method of the ultimate strength of ship hull girders, considered the double bottom and upperwing tank to ship ultimate strength contribution, first defined the stress distribution of the whole section of the ship girders. that is : in the sagging condition, deck and side shell of nearby deck remain the ultimate bucking strength, double bottom remain the yield stress. and the other parts keep elasticity
本文沿用caldwell等人直接計算船體極限強度的思想，考慮雙層底和頂邊水艙對船體極限強度的貢獻，首先將船體梁整體破壞時剖面應力分佈確定為：在中垂狀態下，甲板及甲板附近的舷側均屈曲，雙層底區域則均屈服，其他部分保持彈性狀態；在中拱狀態下，雙層底及之間的底舷側均屈曲，甲板及頂邊水艙區域均屈服，其他部分則保持彈性狀態。For this purpose, a simple method was proposed to simulate the progressive collapse behavior of a ship ' s hull girder subjected to longitudinal bending. in this method the cross section of hull girder is divided into small elements composed of a stififener and attached plating
傳統上，船體總縱強度是通過比較許用應力和在名義垂向波浪彎矩作用下甲板或船底上距中和軸最遠點的彈性應力來進行評估的。Firstly, it needs to separate the girder hull into many elements - pulled one and pushed one. secondly, when the ship is in hogging or sagging, you should assume one curvature value so you can get the moment value of every element at this curvature. and then you may add up all the moment of every element
當船體梁在中垂或中拱狀態下時，假定一個初始曲率，根據各個單元對瞬時彈性中和軸彎矩的貢獻，累加得到相對于這個曲率的總彎矩，然後判斷彎矩是否達到極值，如未達到，則增加曲率，重復上述過程，直到彎矩為極值為止。
