“…In order to investigate the seismic behavior of the hybrid coupled PEC wall, Zhou et al [38] carried out quasi-static tests on two 2/3-scaled threestory specimens (PEC-1 and PEC-2, refer to Figure 4) and established the refined finite element model in ABAQUS. The simulation adopted ABAQUS Explicit without the problem of convergence for quasi-static analysis.…”

“…Therefore, the models of the wall used in this paper were established using the above-mentioned modeling method and carried out parameter analysis. Details of the test specimen and the corresponding finite element modeling process can be found in Zhou et al [38] But for the convenience of reading and understanding, the process of establishing the model was briefly introduced in this section. C3D8R, S4R, and B31 were used to simulate concrete, steel plates, and U-shaped stirrups, respectively, in the hybrid coupled PEC wall.…”

Partially encased composite (PEC) members are novel composite members that efficiently exploit the advantages of mechanical properties of concrete and steel. However, the application of PEC members is limited to low-and mid-rise buildings. To overcome this limitation, a study was conducted to assess the seismic performance of a newly proposed steel-concrete hybrid coupled wall consisting of PEC wall piers coupled by means of steel beams. Parametric analysis was conducted to investigate the elastic coupling ratio (CR elastic ) and the way of changing CR elastic on the seismic behavior of the hybrid coupled PEC wall. The results showed that the CR elastic was the main parameter that affected the seismic performance of the wall. The way of changing CR elastic had little influence on the trend of the energy dissipation capacity and strength reservation of the wall. The failure mode and the development of plastic hinges of the wall were also not affected by the way of changing CR elastic . Both too large and too small CR elastic were detrimental to the seismic performance of the wall.To form an ideal plastic hinge development mode and experience good seismic performance, it is suggested that the reasonable range of CR elastic for the wall was 60%-70%.elastic coupling ratio, numerical simulation, partially encased composite member, seismic behavior, steel-concrete hybrid coupled wall | INTRODUCTIONPartially encased composite (PEC) members are a new type of composite structural members with high efficiency and extensive utilization of the advantages offered by concrete and steel. PEC members not only have the merits of high load capacity, good deformation capacity, excellent seismic performance, and fire resistance but also have the advantage of simplified connection details between concrete and steel members; thereby, they fully realize an industrialized mode of construction and assembly. [1][2][3][4] So far, numerous studies have been conducted on PEC beams and columns. [5][6][7][8][9][10][11][12][13] Mucedero et al. [5] reported that the pushdown curve of the structure with PEC beams showed the feature of monotonically increasing due to apparent catenary action. Piquer and Hernández-Figueirido [13] found that the PEC column had good fire resistance and economy compared with the steel column with or without protection. However, because of the limitations imposed by the rigidity of frame structures, the scope of application of existing PEC structures is limited to mid-rise and low-rise buildings in seismic regions. Therefore, in order to broaden the applications of PEC structures and meet the requirements of high-rise buildings in terms of their seismic performance, research on PEC shear walls is gradually being conducted. The preliminary results have showed that PEC shear wall has a full and stable hysteresis curve, excellent energy dissipation capacity, and good seismic performance. [14][15][16]
