A new type of self-centering precast concrete (SCPC) frame with hysteretic dampers is developed to obtain sufficient self-recovering and energy consumption characteristics. The working principle of a novel connection is presented, and seven cyclic loading tests with different parameters on three full-sized novel beam-column joints are investigated. Adequate seismic performances were experimentally observed in cyclic loading tests. Numerical simulation of the novel connection was performed using the OpenSees software. The elaborate simulation results and test results were well matched, such as the hysteretic behaviors, prestressed tendons forces, energy consumption and self-recovering characteristics. Furthermore, a prototype structure was modeled, and the elastoplastic dynamic responses at the design-basis earthquake (DBE) and the maximum considered earthquake (MCE) levels were studied. The results showed that the peak and residual interstory drifts (θ_max and θ_r,max) achieved desirable demands. The post-tensioned strands avoided excessive yielding at the MCE level, and the novel frame had an adequate energy consumption behavior. In addition, incremental dynamic analysis and vulnerability analysis were performed. The 50-year exceedance probabilities of the Immediate occupancy (IO) and Repairable (RE) limit states taking θ_max and θ_r,max as the evaluation indicators were also calculated, respectively. The results demonstrate that the novel frame has adequate seismic performance, greater reliability and less damage potential than the traditional self-centering precast concrete (SCPC) frame without energy dissipation devices.

开发了一种新型的带有滞回阻尼器的自定心预制混凝土（SCPC）框架，以获得足够的自恢复和能耗特性。提出了新型连接的工作原理，并研究了三个全尺寸新型梁柱节点的七个不同参数的循环荷载试验。在循环载荷试验中，通过实验观察到了足够的抗震性能。使用OpenSees软件对新型连接进行了数值模拟。精心设计的仿真结果与测试结果非常吻合，例如滞后行为，预应力筋力，能耗和自恢复特性。此外，对原型结构进行了建模，研究了设计基准地震（DBE）和最大考虑地震（MCE）水平下的弹塑性动力响应。结果表明，峰间和残余层间漂移（θ_最大值和θ _R，最大）来实现期望的要求。后张紧的钢绞线避免了MCE级别的过度屈服，并且新颖的框架具有足够的能耗行为。此外，还进行了增量动态分析和漏洞分析。在现房（IO）可修（RE）极限状态的50年超越概率取θ_最大和θ _R，最大还分别计算了评价指标。结果表明，与不带耗能装置的传统自定心预制混凝土（SCPC）框架相比，该新型框架具有足够的抗震性能，更高的可靠性和更少的破坏潜力。
