为实现对新型侧板加强型连接组合节点的高效分析，提出梁-柱-板组合节点宏观力学模型，确定楼板与钢梁连接的最优实现方法，验证了组合节点宏观模型的准确性和可靠性。建立6层3跨的传统侧板加强型梁柱连接节点框架模型（TSP）、新型侧板加强型梁柱连接节点框架模型（FBSP）和新型侧板加强型梁柱连接组合节点框架模型（CJ-FBSP），对3种考虑实际节点性能的框架模型开展了弹塑性时程分析，获得不同框架模型在地震波作用下的顶点位移时程曲线、层间位移角、塑性耗能及塑性铰分布等。结果表明：根据所提的弹簧刚度计算方法，可以很好地模拟TSP和FBSP裸钢梁节点的性能；同时，考虑栓钉剪切滑移和抗拔性能的连接方法，可准确地模拟组合节点的受力性能；3种节点框架模型的层间位移角均未超过规范限值（1/50）；FBSP框架模型的最大层间位移角小于TSP框架模型但大于CJ-FBSP框架模型，且塑性耗能能力最强；CJ-FBSP框架由于有楼板的加强作用，塑性铰出铰率最小，塑性耗能能力较弱。

To realize the efficient analysis of composite joints with novel side-plate reinforced connections, a macro model of beam-column-slab composite joint was proposed. The optimal realization method of the connection between floor and steel beam was determined. The accuracy and reliability of the macro model was verified. Furthermore, a beam-column joint frame model with traditional side-plate reinforced connections (TSP), a beam-column joint frame model with novel side-plate reinforced connections (FBSP), and a composite joint frame model with novel side-plate reinforced connections (CJ-FBSP) were established. Elastic-plastic time-history analysis was conducted on three frame models considering the joint performance. The top point lateral displacement, inter-story drift angle, plastic energy dissipation, and plastic hinge distribution of different frame models under seismic waves were obtained. The results show that the performance of TSP and FBSP joints can be well simulated according to the spring stiffness calculation method. At the same time, the connection method considering the shear slip and pull-out performance of studs can precisely simulate the mechanical performance of composite joints. The inter-story drift angle of the three joint frame models do not exceed the specification limit (1/50). The maximum inter-story drift angle of FBSP frame model is smaller than that of TSP frame model but larger than that of CJ-FBSP frame model, and the plastic energy dissipation capacity is the best. Due to the strengthening effect of the floor, the plastic hinge rate of CJ-FBSP frame model is the smallest but the plastic energy dissipation capacity is weak.
