“…In 2012, Zhou et al [38] conducted tests on 9 PEC stub-columns under axial load and found that the failure of PEC columns was caused by local buckling of flanges and concrete crushing. In 2013, Begum et al [39] studied the performance of PEC column with high strength concrete through finite element analysis. The results showed that using high strength concrete (60 MPa) instead of ordinary concrete (30 Mpa), the bearing capacity of PEC column was increased by about 55%, but the load-displacement curve exhibited brittle failure.…”

A steel plate shear wall often uses partially encased composite (PEC) columns instead of edge frame columns. Such a steel plate shear wall not only bears the gravity load of the structure and resists the bending moment caused by lateral force by taking advantage of the high bearing capacity and bending stiffness of PEC columns, but also effectively anchors with the frame column to counteract the tension field generated by the steel plate. Therefore, the performance of the steel plate shear wall after buckling can be fully exerted and the seismic performance of the structure can be improved. In order to investigate the seismic performance of the structure, a 1/3-scale specimen test of steel plate shear wall with PEC columns is designed and fabricated, and a finite element model is established with the same size of test. It is found that the test and simulation results are in good agreement, which confirms the reliability of the simulation. Subsequently, 20 models with different parameters of steel plate shear wall with PEC columns are analyzed using ABAQUS. Finally, the failure mode, hysteretic behavior, skeleton curve, and bearing capacity of steel plate shear wall with PEC columns are obtained. The results show that PEC columns have a good anchoring effect on the diagonal tension field and can fully exert the plasticity of the infill steel plate, so that steel plate shear wall with PEC columns has superior seismic performance. Experiments also reveal that the crack type of damages appear in a steel plate shear wall with PEC columns, and, as a future work, the authors will explore the use of structural health monitoring methods, such as piezoceramic transducer-based method, to monitor such cracks.

“…It was found that the ultimate load achieved decreased with the increase of slenderness ratio. Saima et al [45] studied the behavior of slender partially encased composite column, PEC, using Newmark's iterative procedure to identify the potential variables that can significantly affect the behavior of slender column. It was also found that the eccentric axial capacity of the column has been reduced prominently as the overall slenderness ratio increased.…”

“…It has great potential as a seismic-resistant solution if properly designed to exploit the stiffness contribution of the concrete material and the dissipative capacity of the steel components. Meanwhile, the PEC structure has excellent fire resistance and can be assembled directly in the field after processing in factories [1][2][3][4]. Currently, the behaviour of PEC columns and PEC beams has been widely studied [5][6][7][8][9][10].…”

This paper proposes a hybrid coupled partially encased composite (PEC) wall system, obtained through the connection of two PEC walls by means of the shear critical steel coupling beams with an innovative welded connection. This structural solution is designed to take advantage of both the stiffness of the PEC walls (required to limit building damage under frequent earthquakes) and the ductility of the steel coupling beams (necessary to dissipate energy under medium-intensity and high-intensity earthquakes). The connection performance of an innovative rigid joint with different configurations in this system is studied through pseudostatic analysis, and the seismic performance of the proposed hybrid coupled PEC wall system is evaluated through multirecord nonlinear dynamic analysis of a set of case studies. Adopted finite element models are developed and validated against the available experimental results. A summary of the results is presented and discussed to highlight the potential of the proposed hybrid coupled PEC wall systems. The key feature of this system is development of a reasonable two-level yielding mechanism (the first level is the yielding of the coupling beams, and the second level is the yielding of the PEC wall) without damage to the welded joints.
