This study presents shear resistance of precast reinforced concrete (RC) shear walls. A novel assembling method for upper and lower wall panels is proposed, whereas vertical steel bars are grouped into bundles and effectively connected in preformed holes. To evaluate the feasibility and shear resistance of such a connection method, three specimens of precast shear walls with different horizontal steel bars have been constructed and tested under monotonic loading while subjected to a constant vertical compression. The results show that cracks mainly appear under the line that connects the midpoint of tension side and the corner of the compression side. The weak section of these shear walls is at the top of the preformed holes, and through cracks do not appear at the bottom of walls. These innovative precast shear walls are reliable, and no rebar is pulled out or seriously slipped. The yield load of the shear wall is great, and the stage between yield and failure is satisfactory. The bearing capacity declines slowly after the peak value.

新型捆绑连接预制RC剪力墙抗剪试验研究

本研究介绍了预制钢筋混凝土 (RC) 剪力墙的抗剪强度。提出了一种新的上下墙板组装方法，将垂直钢筋分组并在预制孔中有效连接。为了评估这种连接方法的可行性和抗剪能力，我们建造了三个具有不同水平钢筋的预制剪力墙试件，并在单调荷载下进行了测试，同时承受恒定的垂直压缩。结果表明，裂缝主要出现在受拉侧中点与受压侧角部连线下方。这些剪力墙的薄弱部分位于预制孔的顶部，在墙的底部不会出现贯穿裂缝。这些创新的预制剪力墙是可靠的，无钢筋被拉出或严重滑脱。剪力墙的屈服荷载很大，屈服与破坏之间的阶段令人满意。达到峰值后承载力缓慢下降。
