中文摘要：

主要对基于摇摆柱的海洋平台进行低周往复分析和静力推覆分析,采用Pinto钢本构,运用Ansys建模进行仿真分析,采用静力推覆法模拟冰力,研究新型基于摇摆柱的海洋平台抗震性能并与原海洋平台进行对比,分析基于摇摆柱的海洋平台和原海洋平台的弹塑性性能和极限承载力性能.

英文摘要：

The paper makes a study of the offshore platform based on rocking column with simulation methods of low cyclic analysis, Push-over analysis, and Pinto steel constitution. The model is made and simulated by Ansys, the method of Push-over is used in the simula-tion of sea-ice stress. By analysis of the seismic resistance capacity, it compares the differen-tiation between the primary offshore platform and the offshore platform on the elastic-plastic capacity and the ultimate bearing capacity.
