【摘要】 采用OpenSees有限元系统作为分析工具,本文针对一个钢筋混凝土框架结构的振动台模型试验,选取了几种典型工况进行了数值模拟研究。数值模拟研究包括结构动力特性的分析、弹性及弹塑性时程分析,并给出了结构塑性发展历程。模型实测与理论计算响应结果对比分析表明:振动台模型试验实测结果与理论计算值吻合较好,说明文中所采用的分析模型及方法是可行的,可以作为振动台结构模型试验的分析工具。更多还原

【Abstract】 Numerical simulation of a 4 story RC frame shaking table test model was carried out using of OpenSees finite element analysis system in this paper.Numerical simulation results include elasto-plastic time history analysis and plastic hinge evolution.It was concluded from comparisons between experimental results and numerical simulation results that numerical simulation results are consistent with experimental results.更多还原
