| 摘 要： | 为研究新型全装配RC楼盖发卡式板缝节点的抗剪性能,进行了发卡式板缝节点平面内单调和低周反复荷载下的足尺模型试验,对发卡式板缝节点的裂缝模式、破坏过程及形态、荷载-位移关系曲线和耗能能力等进行了较为系统的研究。结果表明:发卡式板缝连接节点滞回曲线饱满、耗能性能好,具有较好的抗震性能;可采用拉压杆模型理论将企口板两侧连接件抗力叠加来计算节点抗剪承载力。

EXPERIMENTAL STUDY OF SHEAR CAPACITY OF HAIRPIN SLAB CONNECTION IN PRECAST RC FLOOR |
| |
| Abstract: | An experimental study consisting was conducted to evaluate the shear bearing capacity of hairpin slab joints used in new-type precast concrete floor diaphragm. Crack and failure mode,load-displacement relationship curves, energy dissipation capacity of the test specimens was evaluated. And the test results reviewed that the hysteretic curves of hairpin connection was full,which showed good energy dissipation and seismic performance. The in-plane shear bearing capacity of the hairpin slab joint which consisted of couple arranged hairpin mechanic connectors in both side of the slab can be predicted in superposition method based on stud-and-tie mode theory. |
