## 4 Conclusions  
This paper presents a comparative study on the in-plane seismic behavior of four single-story RMSWs under reversed cyclic loading. The effects of construction method and cross section on the seismic performance were evaluated according to displacement ductility, stiffness degradation, energy dissipation, and equivalent viscous damping. The following conclusions can be drawn:  
1. All the walls presented diagonal shear failure. The stepped cracks along the bed joints and vertical joints and diagonal crack crossing the units and mortars were observed. The first sets of visible diagonal cracks in the prefabricated walls were located at both segments at the wall ends. Furthermore, the cracks in the cast-in-place specimens were mainly distributed in the lower half of the walls. The grout in the first course of the wall peeled off because of the lack of protection from unit face shells where the vertical rebar overlapped. This illustrated that the use of cleaning-hole units and overlapped reinforcement changed the crack distribution. 2. All the test specimens displayed symmetric behavior until the peak load. The lateral capacity of PCMWT and CMWT with a T-shaped section was 21% and 7% higher than that of the corresponding rectangular sections of PCMW and CMW, respectively. Regarding the construction method, the lateral capacity of PCMW and PCMWT was 12% and 27% higher than that of the corresponding cast-in-place walls, CMW and CMWT, respectively. 3. The equivalent displacement ductility varied between 2.3 and 3.8, which is related to the studied parameters of construction method and cross section. The displacement ductility of prefabricated walls was 41% and 39% higher than that of the cast-in-place walls regarding flanged and rectangular cross sections, respectively. Furthermore, the displacement ductility of the flanged walls was 19% and 17% higher than that of rectangular walls for prefabricated and traditional construction techniques, respectively. 4. The initial stiffness of the test walls in this study was predominantly influenced by the cross section. The T-shaped cross section increased the initial stiffness of the specimens by 62% compared to that of rectangular walls. The secant stiffness decreased sharply at low values of drift and then dropped slowly at high values of drift. Additionally, the stiffness of specimens with flanges decreased more rapidly than did that of cast-in-place walls until the first major diagonal crack occurred. 5. The slope had an obvious increase when the first major diagonal crack occurred. The cast-in-place walls had higher energy dissipation capacity than did the prefabricated ones at the same lateral drift. The T-shaped cross section improved the energy dissipation capacity compared to that of the rectangular section. Then, the equivalent damping ratio dropped rapidly to approximately 0.10 and finally remained stable at a value of 0.13 and 0.26 for prefabricated and cast-in-place walls, respectively.
