“…Figure 10 Preview of the stress distribution on the members of composite plate shear wall system [3] If the composite plate is correctly designed (yielding occurs before buckling) axial force appearing within the frame column would be equal to sum of vertical loads and shear stresses from panel as presented in Fig. 10c, where its value might be determined through Eq.…”

“…Compared to steel plate shear walls, composite plate systems provide more stiffness, greater strength and better energy dissipation capacity for the same steel plate thicknesses. Additionally, during more frequent low and moderate size seismic events composite plate shear walls preclude steel plate buckling and concrete cracking where both might cause periods of occupancy interruption due to the necessary repairs [3].…”

Subject reviewApplication of vertical stabilisation systems composed of frames with infilled panel has been increasingly adopted in nowadays buildings, primarily due to high resistance as well as their favourable behaviour when exposed to significant seismic activity. This paper has covered systems consisting of composite panels placed within the steel or composite member frames. These systems are listed in leading world norms, but the given guidelines are, due to insufficient research, very scarce and leave the designer with a number of opened questions. Aside these guidelines, this paper provides their additional clarification, and indicates the field's current state of the art which would be used to set the course of further research.

U radu su obrađeni sustavi sa spregnutim ispunom, te okvirom izvedenim od čeličnih ili spregnutih elemenata. Takvi su sustavi navedeni u normama, ali su dane smjernice, iz razloga nedostatne istraženosti, vrlo šture i ostavljaju mnogo otvorenih pitanja. Rad uz smjernice iz vodećih svjetskih normi navodi pojašnjenja istih, te dodatno ukazuje na sadašnje stanje područja na temelju čega je moguće iščitati smjernice za buduća istraživanja.Ključne riječi: posmične stijene; seizmičko djelovanje; spregnuti ispun od čelika i betona; vertikalna stabilizacija

“…On the basis of the energy method, Arabzade et al proposed a theoretical model for calculating the elastic buckling coefficients of C‐SPWs characterized by the concrete panel attached to one side of steel plate . This theoretical model was validated with a comparison with experimental results . Using the Galerkin method, Lopatin and Morozov performed a theoretical research on the buckling of a rectangular sandwich plate with all edges fully clamped under uniaxial compressive loading .…”

Summary Composite steel plate shear walls (C‐SPWs) are composed of an infill steel plate and reinforced concrete encasements. With an adequate thickness, the concrete encasement can effectively prevent the premature buckling of the infill steel plate. Researchers have provided nonconservative concrete thickness demands through analyses of approximate elastic buckling, for which the analytical model is too simplistic to simulate C‐SPW buckling. In this paper, the buckling of C‐SPW is addressed using a nonlinear finite element method. To assist this method, a formula for the buckling strength of C‐SPW is theoretically developed. Utilizing the results of nonlinear finite element analysis on C‐SPW, the effects of concrete panel thickness, concrete elastic modulus, infill steel plate thickness, panel aspect ratio, and stud spacing on the infill steel plate buckling are analyzed, and the critical drift ratio corresponding to the buckling of the infill steel plate is obtained. According to the criterion that the C‐SPW will not buckle until its drift ratio achieves the drift limit (0.4%), the minimum concrete panel thicknesses demands are captured from finite element analysis. Fitting these predicted minimum concrete thicknesses, an available formula is proposed for the concrete thickness demand in the design of C‐SPW.

“…Using high strength concrete also decreased the damage of the reinforced concrete panel. Furthermore, arranging the reinforcement in directions of 45° and 135° was found to be one of the ways to decline diagonal cracks . Another CSPSW with two reinforced concrete panels was tested by Guo et al However, during the experimental study, at 2% drift, a column of the specimen fractured, and the test was terminated.…”

“…According to the mentioned studies, the damage to the reinforced concrete was several diagonal cracks with the angle of roughly 45° or 135°. The cracks were perpendicular to each other and had an “X” shape . The main reason is that the concrete panel prevents the out‐of‐plane buckling of the infill steel plate; as a result, several tension cracks spread out on the panel .…”

Summary In this research, seismic performance of composite steel plate shear walls (CSPSWs) using high performance fiber reinforced concrete (HPFRC) panels is experimentally and numerically investigated. Three one‐story one‐bay CSPSW specimens using precast HPFRC panels were designed and fabricated for cyclic quasi‐static experiments. The HPFRC panels of composite shear wall specimens did not have any steel rebars. The main purpose of the study was to understand the effects of rigid and semirigid HPFRC panels on the seismic behavior of the system. Shear capacity, ultimate shear strength, lateral stiffness, energy dissipation, and ductility ratios of the specimens are evaluated. The experimental results demonstrate that specimens were able to resist lateral load up to at least interstory drift of 6%. Using HPFRC panels, CSPSW specimens becomes stiffer in the elastic region, and the yield displacement of the shear wall is decreased; therefore, the ductility ratio of the system is increased. It should be noted that ultimate shear strength, initial elastic stiffness, and energy absorption of specimens with an HPFRC panel on one side or both sides of the infill steel plate were approximately the same. However, using two HPFRC panels is not economical in comparison with CSPSW with an HPFRC panel on one side. Additionally, the second panel increases the seismic mass of the structure.
