中文摘要：
该文来源于由清华大学和中国建筑学会抗震防灾分会建筑结构抗倒塌专业委员会组织的钢筋混凝土框架拟静力倒塌实验数值模拟的盲测竞赛。该文采用基于纤维截面的有限元模型以及通过修正斜压场理论确定节点域受力性能的方法，对钢筋混凝土框架柱、节点以及整体结构的拟静力实验进行了数值模拟，对比分析结果表明：分析结果与实验结果吻合较好，分析方法客观、合理、可靠，为以后的结构倒塌实验分析提供了理论指导。
英文摘要：
The study was motivated by the participation in the blind prediction contest of the RC frame quasi-static tests organized by Tsinghua University and Professional Committee of Collapse-prevention of Building Structure of Association of Earthquake Resistance and Disaster Prevention, Architectural Society of China. This paper presents the simulation of the nonlinear response of a quasi-static test of RC columns, RC beam column joints and a RC frame under inverse triangle loading. A finite element model based on the fiber section is used for beam and column specimens. A macro model is used for a beam column joint specimen and its material behavior is identified by modified compression-field theory. The results show that the simulation results agree well with the test results. The analytical method is reasonable and reliable, thusly it provides guidelines for the analysis of structural collapse tests.
