摘　　要：OpenSees是一个进行有限元分析、有限元反应灵敏度分析以及有限元可靠度分析的集成计算平台,它具有开源性以及灵活的构架性等特点。目前,国内外普遍用OpenSees进行钢筋混凝土结构、桥梁、岩土工程等方面的研究。文中详细介绍了使用OpenSees进行框架结构建模、对梁柱单元进行纤维化以及对其进行时程分析的过程,并通过与其它软件的分析结果进行对比验证了OpenSees分析过程的正确性。OpenSees is a integrated computing platform which combine finite element analysis finite element response sensitivity analysis and finite element reliability analysis. It has the characteristics such as open source and flexible framework, At present, the domestic and foreign generally use OpenSees to study the reinforced concrete structure, bridge, rock and soil engineering etc, The process is described by building a frame structure modeling, fibrosis on beam column element and the time history analysis by OpenSees. The correctness of the analysis process of OpenSees is verified through the analysis of the results compared to other software.
