“…In 1983, Thorburn et al [4] applied the theory of tensile field to thin steel plate shear walls. Since then, many types of thin steel plate shear walls were developed, including unstiffened, stiffened, buckling-restrained, perforated, composited, low-yield-point steel or aluminum [5][6][7][8][9][10], and metal shear panels show good performance [11]. Among them, unstiffened steel plate shear walls are the most basic and common.…”

The paper proposes partially connected steel plate shear walls, in which the infill plates and frames are connected by discretely distributed fish plates at the corners and at the centers. The high lateral resistance of a steel plate shear wall has led to its widespread use in the design of structural shear resistance. In this paper, finite element models of the partially connected steel plate shear walls are established by the finite element method, and the effect of the different partial connections on the shear strength is firstly investigated. Moreover, the variation of the shear strength with the plate-to-frame connectivity ratio is analyzed numerically, and the effect of the connectivity ratio on the development of the tensile field is studied. Based on the numerical analysis results, the effect of the connectivity ratio on shear strength is evident at low levels. When the connectivity ratio is over 80%, the shear strength of the partially connected steel plate shear wall can reach 95% of that of the fully connected steel plate shear wall. When the connection ratio is at a low level, the advantages of the central connection on the shear strength of the structures are higher than those with corner connections. Furthermore, the fitting formula for the partially connected steel plate shear wall is obtained by changing the connectivity ratio and width-to-height ratio of the examples, which can predict the shear capacity of the partially connected steel plate shear wall with different partial connections.

“…The use of SPSW improves the rigidity of the structural element greatly. The SPSW installation in the systems would also reduce the buildings values of inter-story drift and increases in horizontal load-bearing capability and strength of RC frames significantly [1].…”

In high-rise buildings, shear walls are an important structures feature for sustaining lateral forces. The production of prefabricated steel frames buildings will effectively overcome iron and steel spare capacity, allowing the building sector to recover the industrial revolution. As an advanced kind of flexural rigidity steel plate shear walls (SPSWs) can withstand majority of the load in the frame structure, boost the preliminary lateral toughness and lateral bearing strength, and serve as a first protective barrier until the main frame is demolished, reducing the main frame's failure level and improving the structure's failure resistance. When structures are subjected to external loads such as earthquakes, wind, and other natural disasters, shear walls can be used to increase the structure's strength and safety. The main focus of this research is to use SAP2000 to compare and analyze two different types of shear walls in two different 7-story buildings. Two structural members, one having a honeycombed steel sheet sandwiched between two thin steel plates shear wall and the other having RCC shear wall are compared based on lateral loading parameters (base shear, displacement story-drift etc.). Using SAP2000, the effects of three main parameters were investigated by Pushover analysis and Time history analysis. From the complete analysis, shear wall with honey combed thin plates is proved to be better against seismic and wind loading as compared to RCC wall as well as honeycombed sheet sandwiched between steel plates is economical and gives more area to the story by occupying less space.

“…However, a thin steel plate is prone to buckle, which has undesirable effects on the mechanical performance of the shear wall [4,5]. A number of methods have been proposed to restrain the buckling of the steel plates, such as applying different forms of stiffeners [6][7][8], providing vertical slits in the steel plate [9][10][11], lowering the yield point [12][13][14], opening holes [15,16], adopting corrugated plate web [17,18], or using steel plate shear wall with self-centering energy dissipation braces [19][20][21], but none of them have the ideal restraint effect.…”

In this study, in a novel buckling-restrained steel plate shear wall (BRSPSW) with out-of-plane deformation spaces, angle steel stiffeners have been installed so as to create gaps between the steel plate and the covering concrete slabs. A finite element model has been developed to analyse the effect of the gap. According to the finite element results, seismic performance of this novel BRSPSW has been tested under cyclic loading at the scale ratio of 1/3. The failure pattern, hysteretic characteristics, skeleton curve, equivalent stiffness, ductility, and energy dissipation have all been systematically analysed. A stiffened steel plate shear wall (SPSW) has also been tested in order to determine the differences between these two steel shear walls in load-carrying capability and the function and significance of the gap. The test results show that the novel BRSPSW does not only significantly enhance the ultimate bearing capacity, stiffness, ductility, and accumulated energy dissipation of the SPSW but also keep the steel plate basically intact at the end of the test. This can be attributed to the existence of the gaps between the infilled steel plate and the covering concrete slabs. The hysteretic characteristics and the strength and deformation characteristics of this novel BRSPSW have been simulated by using the finite element model, and the test results are in good agreement with the finite element results. Hence, the BRSPSW is an excellent steel plate shear wall to be used in high rise structure to resist horizontal loadings.
