“…It was also noted that application of the FRP does not change dramatically the stress distribution within the infill plate at initial stages of testin; however when the plate has yielded, FRP composites layer carries significant loads in the direction of the tension field. Hatami et al [18] carried out experimental and numerical studies and developed equations and graphs regarding the influence of different inclination of CFRP fibres on shear capacity, ductility, energy dissipation and stiffness ratios.…”

Introducing of lightweight lateral load resisting systems, such as steel shear walls (SSW) is very beneficial for multi-storey buildings. Further improvement of such elements via introducing fibre reinforced polymer (FRP) materials is expected to allow increasing of their ultimate load capacity, stiffness and energy absorption. The aim of presented research is to compare the behaviour of modified SSW via inclusion of FRP in infill plate design. Produced and tested samples are three different types: with steel infill plate (control), with FRP infillplate and with hybrid steel/FRP infill plate. All samples are loaded under quasi-static cyclic seismic testing load as defined in ATC 24 protocol (ATC 24, 1992). The highest ultimate load capacity and lowest stiffness degradation is achieved for sample with glass FRP infill plate, followed by hybrid (carbon FRP/steel and glass FRP/steel) samples. Highest cumulative energy absorption for predominant part of the investigated amplitudes was achieved forhybrid samples. The obtained results indicate that the innovative shear walls with FRP and hybrid infill plates offer excellent load capacity and energy absorption, relatively small loss of stiffness and potential for increased durability in comparison with conventional SSW systems.

“…Use of CFRP in laminating steel plates was initially investigated by Hatami and Rahai 131 [19]. They concluded that HSW with CFRP/steel infill plates in comparison with steel shear 132 walls have higher energy dissipation and enhanced elastic stiffness and shear capacity [19].…”

28In this study new types of advanced hybrid shear wall systems using steel/fibre reinforced 29 polymer (FRP) composites are being developed for deployment in the construction of 30 buildings. The hybrid steel/FRP shear walls made from laminates of steel with either carbon 31 FRP (CFRP) or glass FRP (GFRP) materials. In total six medium-scaled shear wall 32 specimens were manufactured. In the first phase of the study three pristine specimens: steel 33 shear wall (SSW-P), hybrid steel /CFRP shear wall (HSCSW-P) and hybrid steel/GFRP 34 shear wall (HSGSW-P) were tested. In the second phase of the project, the specimens 35 tested in phase one were retrofitted and retested; these specimens were identified as SSW-36 R, HSCSW-R and HSGSW-R. The structural repair and strengthening of specimens in the 37 second phase was achieved by replacing the damaged infill plates with new infill plates of the 38 same type, strengthening of the vertical steel frame elements with CFRP laminates and 39

“…The impact of crack on the buckling behavior and also the bearing capacity of thin-wall panels must be considered carefully in the design process. [8][9][10][11][12][13] The behavior of cracked plate is studied by Sih and Lee [14] under the influence of tensile and compressive axial loads. They showed that prebuckling capacity was reduced by increasing crack length.…”

Summary In spite of existing comprehensive studies on the behavior of steel plate shear wall (SPSW), some aspects of the SPSW have remained unknown, yet. One of the important aspects that is unknown is the crack effect on the SPSW behavior in linear and nonlinear zones. Some experimental studies have been reported that SPSWs were fractured due to crack propagation. Therefore, the crack effect on the behavior of SPSW should be accounted in considering of SPSW behavior. Although the effect of crack on the thin SPSW has been investigated to a limited extent numerically, stiffened SPSPW, especially diagonally stiffened SPSW, has not been studied. In doing so, in this paper, the effect of crack effect on the behavior of diagonally stiffened SPSWs is studied parametrically and numerically. Numerical results showed that stiffened walls exhibit better behavior in the presence of crack compared with SPSW in both elastic and inelastic zones. Because crack propagates in nonlinear zone, it has not effective on elastic behavior of diagonally stiffened SPSW. The effect of crack was also presented as mathematical equations to estimate load–displacement curve that are in agreement with the finite element results especially for wall thinker stiffeners.
