## 2 Experimental Setup  
### Specimens Design  
In this experiment, 12 full-scale concrete shear wall specimens are designed and tested. The seismic performance of cast-in-place walls and prefabricated laminated walls are analyzed and compared. The design of the test specimens is divided into two types, namely, the prefabricated whole laminated shear wall (PCF-A) and the prefabricated laminated shear wall with a vertical seam (PCF-C), abbreviated as the whole wall and the seam wall, respectively, in this paper. In the actual construction of the prefabricated structures, an assembly seam is inevitable, because it is impossible to fabricate components in the factory that are as large as the structure needs. Thus assembly seams exist between the prefabricated components. Additionally, the connection treatment is difficult between the reinforcements of prefabricated part and the cast-in-place part of the concrete, resulting in relative weakness in the connection part, such as the place between prefabricated shear wall panels and floor or beams, as well as the seam between shear wall panels, which needs to be strengthened. The corresponding locations in the test are the connection part between the bottom/upper beam and the specimen, as well as the vertical seam in PCF-C. In order to study the influence of different structural measures, the specimens with vertical seams are subdivided into two groups according to the position of the longitudinal reinforcement of the concealed column, which are labeled as I and II. Part of the longitudinal reinforcement of specimens in class I are embedded in the prefabricated part, and the rest are placed in the cast-in-place part, while longitudinal reinforcement of specimens in class II are all arranged in the cast-in-place part. All laminated specimens are 1500 mm \(\times\) 1800 mm in size, and the wall thickness is 250 mm (prefabricated 70 mm, cast 180 mm). The concealed column is designed according to edge member requirements in the Code for Design of Concrete Structures (GB50010-2002) [43]. The concealed column is 250 mm \(\times\) 400 mm in class I, and 180 mm \(\times\) 400 mm in class II. The axial ratio of the specimen is 0.11. The longitudinal reinforcement of the concealed column is symmetrical in its cross-section. The column stirrup is made of the combination of \"U\" shaped hoop and \"L\" shaped closed stirrup, with the stirrup hook of 10d (\"d\" represents the diameter of the stirrup), and a bending angle of 135\({}^{\circ}\). The thickness of the concrete covering layer is 25 mm. In the design and fabrication of these specimens, the connections mentioned above not only meet the requirements about connection and anchorage of reinforcements in Chinese codes, but also learn from the provisions of the Japanese regulations. The HRB400 \(\Phi\)10 @ 150 strengthening reinforcement are arranged at the seams (including the seam between the wall and the beam, as well as the vertical seam in the wall) and mortar fills them. To examine the different interface processing on the cooperation performance of the prefabricated part and cast-in-place part, the inner surface of the prefabricated laminated wall panels receive mapping treatment in specimens whose tail number is 1 or 3 (such as PCFI-A1, PCFI-A3, PCFI-C1, PCFI-C3, PCFII-C1, and PCFII-C3), while the rest are sprayed with a surface retarder. At the same time, for the comparative study, two ordinary cast-in-place reinforced concrete shear wall specimens (SW) are fabricated in two types (one is the whole cast-in-place wall, and the other has a vertical seam), with thicknesses of 200 mm, to ensure that the effective thickness of the specimen is the same as the laminated specimens. The parameters of all of the walls are shown in Table 1, and the design drawings are shown in Figure 1.
