An approach combining U-shaped dampers (USDs) and rocking walls is proposed in this paper to improve the seismic performance of traditional precast reinforced concrete (RC) frames with cladding panels (PRCFCPs): (1) the steel bar and USD connection methods are adopted at the top and bottom of the cladding panels to use the relative deformation between the cladding panels and the main structure and then dissipate the seismic energy and (2) rocking walls are added to the structure to control the structural deformation profiles. The USD numerical model is calibrated using the test data, and a series of nonlinear pushover analyses, dynamic time-history analyses, and incremental dynamic analyses are successively performed to compare the seismic performance and collapse capacity of the PRCFCP, PRCFCP with USDs (PRCFCP-USD), and PRCFCP with USDs and rocking walls (PRCFCP-USD-RW).The results show that the USDs in the PRCFCP-USD-RW undergo more uniform deformation along the structural height and higher energy dissipation efficiency and the PRCFCP-USD-RW exhibits enhanced seismic performance and collapse capacity, which verify the superiority of the proposed combined approach.

通过设置U形阻尼器和摇摆壁来提高带有覆面板的预制RC框架的抗震性能

本文提出了一种结合U型阻尼器（USDs）和摇摆墙的方法，以改善带有覆面板（PRCFCPs）的传统预制钢筋混凝土（RC）框架的抗震性能：（1）钢筋和USD连接方法是在覆层板的顶部和底部采用结构，以利用覆层板和主体结构之间的相对变形，然后消散地震能量，并且（2）摇摆壁被添加到结构中以控制结构变形轮廓。使用测试数据对USD数值模型进行了校准，并依次进行了一系列非线性推覆分析，动态时程分析和增量动态分析，以比较PRCFCP，PRCFCP与USDs（PRCFCP-美元），
