Composite slabs without outer longitudinal reinforcement are a new option for assembled shear walls, which are easier to be transported. However, their performance, especially their seismic behavior, which is crucial to assembled structures, is still unclear. Furthermore, the effect of whether an additional reinforcement is incorporated, and its length on seismic behavior is also unclear. Therefore, it is necessary to experimentally investigate the seismic behavior of precast shear wall–slab joints without outer longitudinal reinforcement (PNOJ). Five hysteresis test schemes were designed in detail, including a precast joint with outer longitudinal reinforcement (POJ), three precast joints without outer longitudinal reinforcement (PNOJ), and a cast‐in situ shear wall–slab joint (CJ). Several critical technologies of production, installation, and connection were systematically summarized. The critical indicators of hysteresis and energy dissipation capacity were revealed by analyzing test phenomena and results. The results demonstrated that the PNOJ had great seismic behavior by incorporating additional reinforcement. Meanwhile, the joint seismic behavior was improved by increasing the additional reinforcement length. As compared to the CJ and POJ, the PNOJ demonstrated good seismic behavior and can be used as a reliable wall–slab connection of assembled reinforced concrete structures.

带有和不带有外部纵向钢筋的预制剪力墙-平板节点的抗震性能

不带外部纵向钢筋的复合板是组装好的剪力墙的新选择，剪力墙易于运输。然而，它们的性能，特别是其地震性能，对于组装的结构至关重要，目前尚不清楚。此外，还不清楚是否加入了额外的钢筋及其长度对地震行为的影响。因此，有必要通过实验研究不带外部纵向加强筋（PNOJ）的预制剪力墙-平板节点的抗震性能。详细设计了五个磁滞测试方案，包括带有外部纵向钢筋的预制节点（POJ），三个没有外部纵向钢筋的预制节点（PNOJ）和现浇剪力墙-楼板节点（CJ）。生产，安装，和连接进行了系统地总结。通过分析测试现象和结果揭示了磁滞和耗能能力的关键指标。结果表明，通过添加额外的钢筋，PNOJ具有很好的抗震性能。同时，通过增加额外的钢筋长度来改善接头的抗震性能。与CJ和POJ相比，PNOJ具有良好的抗震性能，可以用作已组装钢筋混凝土结构的可靠墙板连接。通过增加额外的钢筋长度，改善了接头的抗震性能。与CJ和POJ相比，PNOJ具有良好的抗震性能，可以用作已组装钢筋混凝土结构的可靠墙板连接。通过增加额外的钢筋长度，改善了接头的抗震性能。与CJ和POJ相比，PNOJ具有良好的抗震性能，可以用作已组装钢筋混凝土结构的可靠墙板连接。
