The two‐way hollow core precast panel (TWHCPP) exhibits good seismic performance. In this study, the shear behavior of the TWHCPP shear wall with vertical connections was investigated. Specifically, five shear wall specimens, which comprised one cast‐in‐place shear wall, one TWHCPP shear wall without vertical connections, and three TWHCPP shear walls with vertical connections, were investigated experimentally. The TWHCPP shear walls were also modeled through numerical simulation. The experimental and numerical results indicate that the TWHCPP shear wall specimens with vertical connections exhibit monolithic load‐bearing mechanisms before the peak point, which is similar to the cast‐in‐place shear wall specimen. When the peak point of the TWHCPP shear wall specimen was attained, vertical slits were formed in the vertical connection and major vertical crack regions, which divided the shear wall panel into multiple vertical concrete straps. Subsequently, the load‐bearing mechanism of the TWHCPP shear wall transformed to multiple vertical concrete straps working cooperatively with transverse reinforcements. Therefore, the brittle diagonal tension failure mode could be avoided, and a good hysteretic performance could be achieved. The outcomes of this study are expected to provide a useful reference for the application of the TWHCPP shear wall.

竖向连接双向空心板预制剪力墙抗剪性能试验研究

双向空心预制板(TWHCPP)具有良好的抗震性能。在这项研究中,研究了垂直连接的TWHCPP剪力墙的剪力行为。具体而言,对5个剪力墙样本进行了实验研究,包括1个现浇剪力墙,1个不垂直连接的TWHCPP剪力墙和3个垂直连接的TWHCPP剪力墙。TWHCPP剪力墙也通过数值模拟建模。实验和数值结果表明,垂直连接的TWHCPP剪力墙试样在峰值点之前表现出整体的承载机理,与现浇剪力墙试样相似。当达到TWHCPP剪力墙试样的峰值时,在竖向连接处和主要竖向裂缝区域形成竖向缝隙,将剪力墙面板分成多个竖向混凝土带。随后,TWHCPP剪力墙的承载机制转变为与横向钢筋协同工作的多个垂直混凝土带。因此,可以避免脆性的对角张力破坏模式,并且可以获得良好的滞后性能。预期这项研究的结果将为TWHCPP剪力墙的应用提供有用的参考。可以避免脆性的对角张力破坏模式,并且可以获得良好的滞后性能。预期这项研究的结果将为TWHCPP剪力墙的应用提供有用的参考。可以避免脆性的对角张力破坏模式,并且可以获得良好的滞后性能。预期这项研究的结果将为TWHCPP剪力墙的应用提供有用的参考。
