Abstract: 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.
