###### Abstract  
The concrete shear walls of masonry structures with RC frames on the first story are low-rise shear walls with a height-width ratio of less than 1. The strength, stiffness, and ductility of these low-rise shear walls are not matched, resulting in poor seismic performance. Based on the idea of the passive control theory and multi-seismic defensive lines, the scheme of a masonry structure with RC frames on the first story with a concrete-filled steel tubular (CFST) dampers is proposed in this paper. To explore the seismic mitigation effect of CFST dampers applied to a masonry structure with RC frames on the first story, the seismic performance under low-reversed cyclic loading of the frame with the CFST dampers is first compared with that of the energy-dissipated low-rise concrete shear wall proposed by previous researchers and the ordinary low-rise concrete shear wall. Furthermore, the response of the masonry structure model with RC frames on the first story with CFST dampers and two other comparative structural models under earthquake action are discussed. The results show that a masonry structure with RC frames on the first story with CFST dampers has a fuller hysteretic loop, lighter pinching, better energy dissipation ability, and better seismic performance. Compared with the other two structures, the energy dissipation capacity of the masonry structure with RC frames on the first story with CFST dampers is significantly improved, by 1.25-1.5 times. The amplification effect of the deformation angle allows the CFST dampers to play a significant role in energy dissipation, whereas the main structure still undergoes a small deformation. The CFST dampers can dissipate more seismic energy to protect the main structure from damage and improve the seismic performance of masonry structures with RC frames on the first story. the seismic performance in earthquake areas is limited. At present, seismic design codes in China, Japan, and other earthquake-prone countries have enforced strict restrictions on the use of these structures [6]. However, through investigation and research, it was found that this kind of structure, when reasonable designs and measures are used, has a considerable degree of seismic resistance in the event of a major earthquake [7]. At present, it would be relatively ineffective to impose tighter restrictions. It would be a wise development approach to identify a seismic system that has less impact on the structure's utility and can greatly improve its seismic capacity [8]. In in-depth studies of the seismic performance of structural systems, structural components and systems are required to have energy-absorbing and energy-dissipating mechanisms, and multi-seismic defensive lines are required [9]. Under the action of horizontal seismic load, the structural members enter a nonlinear state in the later stage, and the seismic performance of the members is not only related to their strength, but also their deformation performance. The seismic capacity of the structure cannot be measured only by the load-carrying capacity, but the ability of structural members to dissipate seismic energy should be comprehensively considered and the variation in the different types of energy components accurately analyzed [10]. This basic concept has been confirmed by a large number of earthquake damage examples and results obtained by many researchers [11; 12]. To improve the seismic performance of the concrete low-rise concrete shear wall, many scholars have proposed improvement schemes. [PERSON] et al. [13] proposed a steel fiber high-strength concrete shear wall with vertical slots. This kind of shear wall is made of steel fibers and high-strength concrete, and vertical slots are arranged in the wall panels. In addition, the steel bars are not cut off in the slots. The seismic performance of this steel fiber high-strength concrete shear wall with vertical slots is better than that of ordinary concrete shear walls.
