摘要
将线性结构分析软件系统SACS和非线性结构倒塌分析软件系统ABAQUS有机地结合起来,运用非线性逐步破坏分析方法,对渤海绥中36-1油田某4桩导管架标准海洋平台,在其所在海域环境荷载下的抗震可靠性进行了研究,提出了相应的分析方法。结果表明:该平台的抗震可靠度较大,失效概率很小,结构是安全的;所提出的分析方法是一种较为经济、合理和可靠的分析方法。
In this paper, the linear structural analysis system SACS and the nonlinear ultimate capacity analysis system are well combined and applied. By means of nonlinear pushover damage analysis method, the earthquake reliability of a new standard jacket platform with four piles located in SZ 36 - 1 field is studied according to its location and environmental loading. The results indicate that the earthquake reliability of this platform is very high and the failure probability is very low. Also it is proved that the analysis approach proposed in this paper is rather lost effective, reasonable and reliable.
