Abstract This paper addresses the influences of control devices on the seismic responses of rocking wall-frame building structures based on dimensional analysis. Firstly, the flexural-shear beam is adopted to represent the rocking wall-frame buildings, and the control elements include concentrated control devices (CCD, e.g., precast tendons) and distributed control devices (DCD, e.g., dampers installed at floors). Particularly, the closed-form solutions are derived for the static and dynamic responses of the flexural-shear beam with concentrated and distributed control devices. Dimensional response analysis of rocking wall-frame buildings based on intrinsic scale shows that, the normalized seismic responses present complete self-similarity and harmonious order. Then, the vibration characteristics and static responses of the flexural-shear beam are examined. Results indicate that the fundamental period of rocking wall-frame buildings clearly decreases with strengthening DCD. The base moment resisted by the rocking wall remarkably increases with strengthening CCD, and both devices lead to a notable increase in the base shear of the rocking wall. Finally, the dimensional response analysis of rocking wall-frame buildings under near-fault pulse-like ground motions illustrates that, DCD generally suppresses interstory drift response sufficiently, but causes a significant drift concentration. In contrast, CCD does not clearly reduce interstory drift response, yet sufficiently avoids drift concentration. Additionally, both devices generally are not beneficial to control the floor acceleration responses to near-fault impulsive motions, especially DCD. Thus, the appropriate control device should be selected according to the responses concerned in the practical seismic design of buildings.

近断层脉冲式地震动作用下带有控制装置的摇摆墙框架建筑结构尺寸响应分析

摘要 本文基于量纲分析，探讨了控制装置对摇摆墙框架建筑结构地震反应的影响。首先，采用弯剪梁来表示摇摆墙框架建筑，控制元件包括集中控制装置（CCD，如预制筋）和分布式控制装置（DCD，如安装在地板上的阻尼器）。特别是，采用集中和分布式控制装置为弯剪梁的静态和动态响应推导了封闭形式的解决方案。基于内在尺度的摇摆墙框架结构空间响应分析表明，归一化地震响应呈现完全自相似、和谐有序。然后，研究了弯剪梁的振动特性和静态响应。结果表明，随着DCD的加强，摇摆墙框架建筑的基期明显缩短。随着CCD的加强，摇墙抵抗的基矩显着增加，两种装置都导致摇墙的基剪力显着增加。最后，近断层脉冲式地震动作用下摇摆墙框架建筑物的空间响应分析表明，DCD一般能充分抑制层间漂移响应，但引起显着的漂移集中。相比之下，CCD 并没有明显降低层间漂移响应，但足以避免漂移集中。此外，这两种装置通常都不利于控制对近故障脉冲运动的地板加速度响应，尤其是 DCD。因此，在实际的建筑物抗震设计中，应根据所涉及的响应选择合适的控制装置。
