摘　　要：结构刚度改变会导致结构固有频率变化和结构广义刚度的变化,必然会对结构在波浪中的水弹性响应产生影响。本文在某箱式超大型浮体结构单位幅值正弦规则波和不规则波水弹性响应计算的基础上,假定结构质量分布不变,研究了结构刚度变化对箱式超大型浮体结构水弹性响应的影响,得到了一些有价值的结论。The natural frequency and generalized stiffness of structure will vary with the change of structural stiffness, which will affect the hydroelastic response of structure in waves. By assuming the same distribution of structural mass, the effect of structure stiffness on hydroelastic response is analyzed based on the calculation of dynamic response of a box-typed very large floating structure (VLFS) in regular and irregulous waves and some valuable conclusions are drawn.
