Abstract
Abstract：According to our team experimental study on the joints for the Multibarrel tube-confined concrete column and the reinforced concrete ring beam, The software ANSYS of finite element is used to simulate the behavior of connections in this paper. The simulated hysteretic curves and skeleton curves are compared with the experimental data and good agreement can be observed. Moreover, parametric studied have been carried out to investigate the influences of anchorage length of vertical steel bars for the nodes area, the strength of the concrete for the nodes area, the concrete strength of the frame beam, and the longitudinal reinforcement ratio of the frame beam on the skeleton curves.
