This article investigated the seismic performance of a new type of precast concrete beam-to-column joint with a steel connector for easy construction. Five interior beam-to-column joints, four precast concrete specimens, and one monolithic joint were tested under reversed cyclic loading. The main variables were the embedded H-beam length, web plate or stiffening rib usage, and concrete usage in the connection part. The load–displacement hysteresis curves were recorded during the test, and the behavior was investigated based on displacement ductility, deformability, skeleton curves, stiffness degradation, and energy dissipation capacity. The results showed that the proposed beam-to-column joint with the web plate in the steel connector exhibited satisfactory behavior in terms of ductility, load capacity, and energy dissipation capacity under reversed cyclic loading, and the performance was ductile because of the yielding of the web plate. Therefore, the proposed joint with the web plate could be used in high seismic regions. The proposed joint without the web plate exhibited similar behavior to the monolithic specimen, indicating that this joint could be used in low or moderate seismic zones. Furthermore, the utilization of the web plate was vital to the performance of this system.

钢连接件预制梁柱节点在循环荷载作用下的试验研究

本文研究了一种便于施工的带有钢连接件的新型预制混凝土梁柱节点的抗震性能。五个内部梁柱接头、四个预制混凝土试件和一个整体接头在反向循环荷载下进行了测试。主要变量是嵌入式 H 型梁长度、腹板或加强肋的使用情况以及连接部分的混凝土使用情况。在测试过程中记录载荷-位移滞后曲线，并基于位移延性、变形性、骨架曲线、刚度退化和能量耗散能力研究行为。结果表明，所提出的梁柱节点与钢连接件中的腹板在延性、承载能力、和反向循环载荷下的能量耗散能力，并且由于腹板屈服，性能具有延展性。因此，建议的腹板接头可用于高地震区。不带腹板的建议接头表现出与整体试样相似的行为，表明该接头可用于低或中等地震带。此外，腹板的利用对该系统的性能至关重要。
