In this article, the cyclic behavior of reinforced concrete column–steel beam connections is investigated. In this research, an experimental and numerical study is conducted on the performance assessment of the through-beam connections with two detailing. The model details consist of the tube plate and steel doubler plate for the joints. The results show that the steel doubler plate increases the yielding capacity and initial stiffness of the connection but has no effect on the maximum capacity of the connection. Results show that using tube plate alone could have a good performance and there is no need for doubler plates. Furthermore, in order to model this type of connection with tube plate, modified model based on the Cordova’s proposed model is presented, and the load-cycle repetition on the connection at both specimens is simulated utilizing the OpenSees software by taking into account the bearing distortions and joint shear, and the obtained results are verified with the experimental ones as well.

钢筋混凝土柱-钢梁管板连接建模简化方法

在本文中，研究了钢筋混凝土柱-钢梁连接的循环行为。在这项研究中，通过两个细节对直通梁连接的性能评估进行了实验和数值研究。模型细节包括管板和用于接头的钢制双板。结果表明，钢双板增加了连接的屈服能力和初始刚度，但对连接的最大承载力没有影响。结果表明，单独使用管板具有良好的性能，不需要倍压板。此外，为了模拟这种与管板的连接，提出了基于 Cordova 提出的模型的修改模型，
