摘　　要：针对“超大型浮式结构物概念研究”提出的“深水环形浮式人工港”这一新型uLFs的结构型式，选取ULFS一组典型剖面，在4种不同海况条件下，利用DNV的sEsAM／wADAM和sEsAM／POSTRESP程序，对波浪诱导的剖面剪力和弯矩载荷进行预报。通过计算得到剖面垂向剪力和垂向弯矩的传递函数，并根据其短期统计极值，得到不同海况条件下垂向剪力和垂向弯矩沿肋位方向的分布图。As a new style of Ultra Large Floating Structures（ULFS）, an artificial deep circular floating harbor is proposed during the stage of conceptual research on ULFS. A set of typical load cross sections are selected to predict the sectional shear and bending moments which caused by wave loads. DNV＇s software package SESAM/Wadam and SESAM/Postresp are used to compute the sectional forces and moments of ULFS under four different sea states. As results of calculation, the response amplitude operators（RAO） of vertical sectional shear and bending moments are formed and used to define short term statistics. Based on the extreme values of short term statistics, diagrams are got that depict the distribution of vertical shear and vertical bending monments under different sea states.
