In this paper, nonlinear behavior of strengthened steel plate shear walls (SPSWs) by FRP laminates theoretically and numerically has been investigated. In the first part, a new method, “the composite-plate frame Interaction (C-PFI) method”, has been introduced to predict the shear behavior of the composite steel plate shear wall systems (CSPSWs). In the second part, several models of one-story ...

Failures in FRP-strengthened reinforced concrete (RC) members may occur by flexural failures of critical sections or by debonding of FRP plate from the RC beams. Debonding in the FRP/adhesive/concrete interface region may cause a significant decrease in member capacity leading to a premature failure of the system. There is a need for improved knowledge of the debonding processes under mechanica...

in this paper, nonlinear behavior of composite steel plate shear wall systems, in which steel infill plate is strengthened by fiber reinforced polymer (frp) layers, are experimentally investigated. tests are designed to evaluate the effect of glass-frp layers, layers number of gfrp and orientation of gfrp layers on the stiffness, shear strength, cumulative dissipated energy and other seismic pa...

. this paper presents the results of an experimental investigation on shear strength enhancement of reinforced concrete deep beams externally reinforced with fiber reinforced polymer (frp) composites. a total of six deep beam specimens of two different classes, as-built (unstrengthened) and retrofitted were tested in the experimental evaluation program. two composite systems namely carbon/epoxy...

Masonry infill walls are often used as non-structural elements. According to the past structural failure, ignorance of interaction between infill walls and enclosed frame may lead to the different seismic response for non-ductile building frames. The main contribution of this paper is to analytically investigate the behavior of reinforced concrete with masonry infill panels as participating str...
