| 摘 要： | 通过对暴雨荷载下,西北海湾中简易护套、顶托、布局等坍塌行为的对比,研究了平台布置与结构可靠性的关系。采用两种不同性能分析的方法确定极限强度,对确定的结构,给出了截然不同的RSR值。评估了上部重量变化对结构可靠性的影响,结果发现可靠性与结构的布局有关,这种影响在现行的指南中没有提及。研究也显示在不同的平台布局以及相同环境下,同一组固定荷载和环境荷载因素具有不同的可靠性。而且,在某些情况下,采用工作应力设计方法比荷载-抗力设计系数法可以得到更一致的可靠性结果。

| Abstract: | The relationship between platform configuration and structural reliability is investigated by comparing the collapse behaviour of simple jacket, jack-up and monopod topologies under storm loading in moderately shallow North West Shelf (NWS) waters. Two different pushover analysis methods are used to find the ultimate strength, which give quite different reserve strength ratio (RSR) results for certain structures. The effect on the structural reliability of varying topside weight is also assessed. It is foun... |
