“…According to them, unstiffened SPSWs provide a more ductile response while heavily stiffened SPSWs have a wider yield area, which in turn results in higher energy dissipation. Habashi and Alinia [18] studied the nonlinear response of SPSW systems under lateral loading with respect to the interaction between the infill plates and frame members. They showed that the infill plates are very effective in the initial stages of loading (up to the drift angle of 1%) and absorb substantial part of storey shear.…”

Unstiffened steel plate shear walls (SPSWs) have been in use mostly in recent years. In this numerical study, the buckling behavior of a single-storey single-bay unstiffened SPSW with two pinned and rigid beam-column connections under lateral loading is investigated. The SPSW had different wall aspect ratios (L/h=1, 1.5, 2, 2.5, and 3) and infill plate thicknesses (tw= 3, 5, and 7 mm). Their effect on the buckling behavior of SPSW was examined using buckling analysis in ABAQUS software. Results indicated that with the increase of infill plate thickness, the lateral resistance of unstiffened SPSW system increases, but by increasing wall aspect ratio, its resistance decreases. In both connection designs, the model with L/ h=1 (square-shaped model) showed better ductility and higher stiffness and strength in all three thicknesses. Maximum shear stress responses of SPSW models showed that in pinned design with L/h=1, the most change in shear stress values was 8% when infill plate thickness reached from 5 to 7 mm; while for rigid connection, it was reported as 7% when it increased from 3 to 5 mm. This indicates that in rigid connection, increasing the infill plate thickness has less effect on the increase of lateral resistance. By examining the performance of rigid and pinned beam-to-column connections with different wall aspect ratio and infill plate thickness, it was found out that maximum shear stress in rigid connection increased by 11% compared to pin connection. It was concluded that an optimum unstiffened SPSW model had a wall aspect ratio of 1 and infill plate thickness of 7 mm.

IntroductionIn the past three decades, the steel plate shear wall (SPSW) configuration has been widely used as a lateral load resisting system in the regions of high seismicity. A typical SPSW consists of infill steel plates connected to the beams, known as the horizontal boundary elements (HBE); and to the columns, as the vertical boundary elements (VBE). All HBE-VBE connections are of moment resisting type.Many numerical researches have been and are being carried out to study the behavior of SPSW systems via the four available methods of analysis. Two methods are linear, known as Linear Static Procedure (LSP) and Linear Dynamic Procedure (LDP); and two methods are nonlinear, known as Nonlinear Static Procedure (NSP) and Nonlinear Dynamic Procedure (NDP). The linear procedures are appropriate when the expected level of nonlinearity is low. In the SPSW system, the material nonlinearity is considerable as infill plates yield extensively. Therefore, nonlinear methods are proper tools to study the seismic behavior of such system. The nonlinear dynamic procedure, also known as the nonlinear time history analysis, is deemed to be the most accurate method; but it is complex, expensive and time consuming, especially when there are a large number of elements involved. On the other hand, the nonlinear static procedure, known as the pushover analysis, is a more convenient available method to the structural engineers; and is favored by practicing engineers. The nonlinear pushover analysis accounts for both geometric and material nonlinearities in buildings subjected to seismic loads. It also allows the tracing of the sequence of yielding and failure of members, as well as the progress of overall capacity of structures. On the other hand, prior to a cyclic test or analysis, pushover analyses are performed to predict the maximum strength and deformations of structures in order to develop a suitable loading history, evaluate the needs for instrumentation, establish the range of load and deformation measurements, and reduce the risk of unexpected behavior during experiments [1].In addition to the above mentioned applications, the pushover analysis has two further use in SPSW structures.

Steel plate shear walls (SPSW) consist of thin infill steel plates attached to beams and columns in steel frames. SPSW are efficient lateral load resisting systems and can act as an alternative to traditional systems. In this study, the nonlinear response of single-story single-bay SPSW models having different yield points of infill plates (100, 180, 250 MPa.), were numerically investigated under lateral loading. The other variables in the analysis were the aspect ratio of panels (2 and 2.5), and thickness of the steel plates (3 , 5 and 7 mm.). The models were designed according to the "AISC Steel Design Guide 20" and the "AISC 341-10 Provisions". Finite element models of SPSWs were developed and analysed using ABAQUS nonlinear program. The results show that, using low yield point steel leads to more ductility and with some consideration influence the stiffness of models.
