摘要：

Based on experimental data of composite beam-reinforced concrete column frames, a corresponding finite element (FE) numerical model was established using the OpenSees. By comparing experimental and simulation results, the feasibility of this model was verified. Furthermore, an in-depth nonlinear analysis of the seismic performance of the composite beam-reinforced concrete column frames was conducted. This analysis focused on the effects of various factors such as reinforcement ratio of slabs and columns, the section modulus of steel, axial compression ratio, concrete strength, and steel strength on the load-displacement of the such frames. Ultimately, based on the test and simulation results, a new load-displacement hysteretic model for composite beam- reinforced concrete column frames was derived, and its calculation results were compared with those from the test and simulation. The comparison indicated that the derived formula is in good agreement with the experimental data, demonstrating its applicability in structural calculation and analysis.
