| 为了优化外挂 ALC- 钢框架组合结构的抗震性能，提出了一种新型外挂 ALC 墙板连接节点—组合式摇摆节点。首先对外挂钩头螺栓节点和组合式摇摆节点进行了低周往复加载试验；然后从试验现象、滞回曲线、骨架曲线、刚度退化曲线和耗能曲线分析了两组构件的差异；最后通过有限元软件建立了组合式摇摆节点的模型。试验结果表明：组合式摇摆节点的使用有效减缓了地震荷载对外挂 ALC 墙板的影响，并提高了外挂 ALC 墙板 - 钢框架组合结构的承载力和抗震性能。建立的模型为分析不利荷载对组合结构的影响提供理论支持 |

| In order to optimize the seismic performance of the external ALC-steel frame combination structure，a new type of externalALC wall panel connector - combined swing connector is proposed. First of all，the external hook head bolt connector and the combinedswing connector were tested by low cyclic loading. Then，the differences between the two groups of members were analyzed from the testphenomenon，hysteresis curve，skeleton curve，stiffness degradation curve and energy dissipation curve. Finally，the model of thecombined swing connector was established by finite element software. The experimental results show that the use of the combined swingconnector effectively reduces the seismic loads on the external ALC wall panel，improves the bearing capacity and seismic performanceof the external ALC-steel frame wall panel combination structure，and the established model provides theoretical support for analyzingthe impacts of adverse loads on the combination structure. |
