摘　　要：介绍了非线性分析工具USFOS程序在导管架固定平台倒塌分析中的应用特点,并以某实际平台为研究对象使用USFOS分析程序对其进行了倒塌分析。结果发现平台在90°方向的储备能力最差,其倒塌抵抗力系数RSR值仅为2.01,但仍然满足不低于1.6的设计要求,尽管该导管架平台在达到倒塌最大能力之前部分杆件发生屈曲而产生塑性铰,管节点发生了屈服现象,但平台整体的倒塌冗余度尚能满足设计要求。This paper introduces the application characteristics of USFOS program,a non-linear analysis tool,in the analysis of jacket fixed platform collapse.USFOS analysis program is used to analyze the collapse of a practical platform.The analysis results show that the reserve capacity of the platform in the direction of 90 degrees is the worst and its RSR value is 2.01,but it still meets the design requirements of 1.6.Although some members buckle and produce plastic hinges,and the tubular joints yield before the jacket platform reaches the large capacity of collapse,the overall collapse redundancy of the platform meets the design requirements.
