To avoid the damage of the connection due to the overstrength of beam strength, and the alternation of the strength hierarchy in the structural system, a novel precast concrete beam-to-column connection is proposed herein. In the proposed connection, a novel replaceable energy-dissipation connector (REDC) was placed at the bottom of a hidden corbel. In addition, a narrow vertical slot was placed adjacent to the hidden corbel to reduce the beam overstrength. First, the structural features and mechanical mechanism of the proposed novel precast connection were discussed. Second, three low-cycle quasi-static loading tests were carried out on a single full-scaled specimen by using three REDCs of different sizes. The test results showed that the seismic performance of this novel precast connection was excellent and that the additional bending moment caused by beam overstrength in the novel precast connection was significantly lower than that of a conventional connection. Third, three finite element models were developed to further analyze how to reduce the additional bending moment and to always keep the top reinforcements in the elastic range. Finally, relevant design suggestions were provided. The additional bending moment of the novel precast connection designed according to the proposed formulas can be minimized. In view of this, the bending moments of the novel connection can be regarded as a controllable variable.

为避免梁强度过大造成连接破坏，以及结构体系中强度等级的变化，本文提出了一种新型的预制混凝土梁柱连接。在建议的连接中，一种新型的可更换耗能连接器 (REDC) 被放置在隐藏式牛腿的底部。此外，在隐藏的牛腿附近放置了一个狭窄的垂直槽，以减少梁的过度强度。首先，讨论了所提出的新型预制连接的结构特征和机械机制。其次，使用三个不同尺寸的 REDC 对单个全尺寸试样进行了三个低周准静态加载试验。试验结果表明，这种新型预制连接件的抗震性能优良，且新型预制件连接件中梁超强度引起的附加弯矩明显低于常规连接件。第三，开发了三个有限元模型，以进一步分析如何减少附加弯矩并始终将顶部钢筋保持在弹性范围内。最后提出了相关的设计建议。根据建议的公式设计的新型预制连接的附加弯矩可以最小化。有鉴于此，新型连接的弯矩可视为一个可控变量。开发了三个有限元模型，以进一步分析如何减少附加弯矩并始终将顶部钢筋保持在弹性范围内。最后给出了相关的设计建议。根据建议的公式设计的新型预制连接的附加弯矩可以最小化。有鉴于此，新型连接的弯矩可视为一个可控变量。开发了三个有限元模型，以进一步分析如何减少附加弯矩并始终将顶部钢筋保持在弹性范围内。最后提出了相关的设计建议。根据建议的公式设计的新型预制连接的附加弯矩可以最小化。有鉴于此，新型连接的弯矩可视为一个可控变量。
