Precast concrete structures have satisfactory performances in quality control and construction progress. This article experimentally studied the seismic behavior of a type of precast beam-column connection. Three full-scale specimens are designed with different longitudinal reinforcement ratios and details of connections. Precast beam-column connections are systematically investigated focusing on their failure modes, hysteretic and skeleton curves, strength, ductility, stiffness degradation, and energy dissipation capacity. Test results show that the shear panel damage becomes more serious, and the ductility drops dramatically by 32.3% with the increased reinforcement ratio. Moreover, with the change from service holes to reserved grooves, the ductility of the specimen increases evidently, and the energy dissipation capacity fully developed, increasing by 24.0%. Furthermore, influences of reinforcement ratio and detail of construction on the trend of stiffness degradation showed to be not significant. Research findings could provide guidelines for the popularization and application of this type of precast beam-column connection in reinforcement concrete frame structures.

循环荷载作用下预制梁柱连接抗震性能试验研究

预制混凝土结构在质量控制和施工进度方面表现令人满意。本文通过试验研究了一种预制梁柱连接的抗震性能。三个全尺寸试件设计有不同的纵向配筋率和连接细节。系统地研究了预制梁柱连接，重点关注其失效模式、滞回曲线和骨架曲线、强度、延展性、刚度退化和能量耗散能力。试验结果表明，随着配筋率的增加，剪力板损伤更加严重，延性急剧下降32.3%。而且，随着维修孔改为预留槽，试件的延展性明显提高，耗能能力得到充分发挥，增长 24.0%。此外，配筋率和施工细节对刚度退化趋势的影响并不显着。研究成果可为此类预制梁柱连接在钢筋混凝土框架结构中的推广应用提供指导。
