By proposing a multiple rocking infill wall–frame (MRWF) system, this paper investigates the effects of wall–frame interaction on the seismic response of self‐centering walls. In the MRWF system, infill walls are connected to the adjacent beams through posttensioned tendons, which provide the self‐centering ability, and the energy dissipation capacity of the system is enhanced using O‐shaped steel dampers. The seismic behavior of the MRWF system, with various wall configurations, is evaluated alongside conventional shear wall and typical rocking wall systems at three height levels of two, four, and six stories. After developing the numerical models, the cyclic and time history analyses are carried out. The results of cyclic analysis show that the energy dissipation capacity of MRWF models is much higher than that of typical rocking wall models. Furthermore, for the MRWF models, by increasing the number of walls with a smaller width, the effect of wall–frame interaction is mitigated, resulting in minimal damage to the structural members and self‐centering ability of more than 90%. The time history analysis results illustrate that for the MRWF models, the residual drifts and plastic rotation at the beams are significantly reduced by applying the proper structural layout of the multiple rocking walls, especially for six‐story models.

多层预制混凝土建筑物的后张应力摇摆填充墙框架系统

通过提出多重摇摆填充墙框架（MRWF）系统，本文研究了墙框架相互作用对自定心墙的地震响应的影响。在MRWF系统中，填充墙通过后张拉的筋与相邻梁连接，从而提供了自动居中的能力，并且使用O形钢制减震器增强了系统的能量消耗能力。在两个，四个和六个楼层的三个高度级别上，对具有各种墙面配置的MRWF系统的抗震性能与常规剪力墙和典型的摇摆墙系统进行了评估。建立数值模型后，进行循环和时间历史分析。循环分析结果表明，MRWF模型的能量耗散能力远高于典型的摇摆壁模型。此外，对于MRWF模型，通过增加宽度较小的墙的数量，可以减轻墙框架相互作用的影响，从而使对结构构件的损害最小，并且具有超过90％的自对中能力。时程分析结果表明，对于MRWF模型，通过应用多个摇摆壁的适当结构布局，尤其是对于六层模型，梁的残余漂移和塑性旋转显着减少。
