“…Sabouri-Ghomi and Roberts [17] and Roberts [19] have reported results of 16 tests of steel shear panels diagonally loaded. The specimens in these tests consisted of steel plates placed within a 4-hinged frame and connected to it using bolts.…”

“…The tests indicated that all panels possessed adequate ductility and sustained four large inelastic cycles. Typical hysteresis loops presented in Sabouri-Ghomi and Roberts [17] shows specimens reaching a ductility of more than seven without any decrease in strength. The researchers concluded that the strength and stiffness linearly decreases with the increase in the perforation dimensions.…”

Composite shear walls made of a thin steel plate with reinforced a concrete cover, which is attached to one or both sides of the steel plate, are the third generation of lateral load resisting shear walls. In addition to increasing resistance, ductility and energy absorption, these walls are very economical and are used in constructing tall buildings, resistance of buildings and tanks. In the present research the effect of various thicknesses of steel plate on the behavior of composite shear walls in different shear connectors has been studied. For this purpose, several different models, including moment frames, steel shear walls and composite shear walls, have been analyzed through numerical and experimental models. In composite shear walls, the number of layers of reinforced concrete cover, the distance between the shear connectors and the thickness ratio of steel plate to the thickness of concrete cover are considered as variables. Increasing the thickness ratio of the steel plate to the concrete layer up to optimum leads to reduction in the out-of plane deflection rate of the steel plate and has no effect on the performance of the composite shear wall. In addition, using two layers of concrete cover on both sides of the steel plate decreases the secondary moment.

“…Regarding the experimental results and recommendations of other researchers (Astaneh [8,9]) at least 10 members in the throat were used while creating diagonal strips. The cross section area of these members is in rectangular form and is equal to the distance between two strips; the thickness of the members is the same as the calculated thickness of the design.…”

When an earthquake occurs, the structure will enter into a nonlinear stage; therefore, new approaches based on nonlinear analysis are needed to flourish with the purpose of more realistic investigations on seismic behavior and destruction mechanism of structures. According to the modern philosophy, "Performance-based Earthquake Engineering" is formed in which simple nonlinear static analyses are mostly used in order to determine the structure's behavior in nonlinear stage. This method assumes that the structure response is only controlled by the main mode and the shape of this mode will remain the same, while it enters the nonlinear stage. Both of these assumptions are approximations, especially in high buildings, which have a long period. It seems that constant load pattern used in these methods cannot consider all of the effects properly. In this paper, an attempt was made to study the accuracy of these methods in comparison to nonlinear dynamic analysis, by considering various load patterns existing in FEMA, also load patterns proportional to higher modes in nonlinear static method, and employing an approximative method of MPA modal analysis, study the accuracy of these methods in comparison to nonlinear dynamic analysis. For this purpose, three steel frames of 4, 8, and 12-stories with steel shear wall have been studied.

“…To prevent buckling, engineers designed steel walls with heavily stiffened infill plates that were not economically competitive with reinforced concrete shear walls. However, several experimental and analytical studies using both quasi-static and dynamic loading showed that the post-buckling strength of thin SPSW can be substantial (Thorburn, et al, 1983;Timler and Kulak, 1983;Tromposch and Kulak, 1987;Roberts and Sabouri-Ghomi, 1992;Sabouri-Ghomi and Roberts, 1992;Cassese et al, 1993;Elgaaly et al, 1993;Driver et al, 1998;Elgaaly and Liu, 1997;Elgaaly 1998;Rezai, 1999;Lubell et al, 2000;Berman and Bruneau, 2003a;Vian andBruneau, 2004, Berman and. Based on some of this research, the Canadian Standards Association steel design standard CAN/CSA S16-01 has implemented design clauses for SPSW allowed to buckle in shear and develop tension field action (CSA, 2001).…”

This paper will briefly discuss some of the research that will likely be incorporated into US design codes for the use of steel plate shear wall as seismic load resisting systems. References to numerous research projects carried in the United States, Canada, and other countries will be given and their major findings highlighted. The strip model, developed by others for the representation of SPSW, is described and plastic analysis results for that model and their use in design is discussed. Finally, new directions for SPSW research, including the use of light-gauge and low yield-point steels, strategic hole placement, and reduced beam sections are described in the context of some recently completed and ongoing research.
