## 1 Introduction  
RC structure has been widely applied in the construction industry due to the easy availability of building materials, advanced mechanical properties, and huge economic benefits. However, RC structure does have its disadvantages, such as the large consumption of building materials, huge amount of building waste, heavy pollution, high labor intensity, low degree of industrialization, and so on [1]. Apparently, it does not conform to the national policy of \"Saving Resources and Protecting the Environment\" and \"Building a Resource-saving, Environmentally Friendly Society and Adhering to the Road of Sustainable Development\". Compared with the RC structure, the PC structure has many advantages [2], e.g., high-quality components, fast construction, energy saving, pollution reduction, and low disturbance to the residency. Therefore, the PC structure is one of the key structure types advocated by the Chinese government. For the PC shear wall structure, connection is the key [3; 4]. According to research conducted both at home and abroad, the forms of connection can be categorized into two main types: wet connection and dry connection. At the same time, the effects of the connection and assembling zone on the shear wall have also been studied, since they are likely to affect the mechanical behaviors of the wall. For example, [PERSON] et al. [5] thought that shear walls with different strengths of materials may result in unexpected failure modes, and they emphasized the importance of ensuring compatible material properties. Wet connection mainly includes sleeve grouting connection [6; 7; 8; 9] and lap connection [10; 11; 12; 13; 14]. [PERSON] [15] and [PERSON] [16] studied the influence of sleeve grouting connection on shear walls. The test results show that this type of wall exhibits ductile and stable hysteretic behaviors; furthermore,the effectiveness of sleeve-mortar connections in load transfer is also validated. [PERSON] [17] carried out a quasi-static test on the shear wall with sleeve grouting. The test shows that the sleeve connection is very sensitive to the grouting quality, which can affect the performance of the assembling zone. [PERSON] et al. [18] thought that full pouring is difficult to conduct in the interface of the connector, and horizontal gaps may form in the assembling zone. As a result of this, the ductility and energy dissipation capacity of the structure are reduced. [PERSON] et al. [19] studied the influence of banded and lapped connection on shear walls. The test shows that when the connector is located at the upper part of the wall, the mechanical behaviors of the PC wall and the RC wall are basically the same; but when the connector is located at the bottom of the wall, the wall is prone to severe damage because the load is the largest at the bottom and the connector is unbearable. In summary, the stress of vertical rebars can be effectively transmitted with the wet connection form. However, it is undeniable that this kind of connection is complex in structure and technique intensive. These shortcomings may somehow compromise the advantages of the PC structure, and make the quality of the connection difficult to guarantee. Dry connection mainly includes prestressed connection [20; 21; 22; 23; 24; 25], welded connection [26; 27; 28], bolted connection [29; 30; 31], and anchor connection [32; 33]. [PERSON] et al. [34] considered that if dry connection is correctly designed, the wall may still enjoy a good seismic performance. [PERSON] [35] studied the influence of unbonded post-tensioned prestressed connection on shear walls. The test shows that the strength and initial stiffness of the PC wall are basically equivalent to those of the RC wall, but the energy dissipation capacity looks inferior. [PERSON] et al. [36] used the bolts to connect the PC wall and the ground beam. The result shows that the PC wall with bolts boasts a good ductility and energy dissipation capacity under an earthquake load.
