针对浮式生产储卸油装置(Floating Production Storage and Offloading,FPSO)主船体货舱区域结构采用Abaqus准静态分析法,考虑材料非线性因素和船舶工作海域实际海况,建立3档强框模型并对其在垂向弯矩和30°艏斜浪作用下的极限承载能力进行研究.采用整船波浪直接计算得到的弯矩幅值响应算子比值确定联合载荷中垂向与水平载荷加载关系.研究表明:在垂向载荷作用下结构抵抗中拱弯矩的能力更强;引入水平载荷后结构抵抗垂向外载荷能力降低且水平载荷对中垂极强弯矩的影响更大,极限弯矩发生时相应结构一般发生大面积的屈曲破坏;水平极限弯矩总是先于垂向极限弯矩出现:舭部结构的存在有效传导了中拱与水平弯矩联合载荷.
