“…A similar improvement factor of the limit point load was detected in the experimental study of [Tumialan et al 2003]. Yet, this value is much smaller than the factors experimentally detected for strengthened simply supported and longitudinally unconstrained walls [Gilstrap and Dolan 1998;Albert et al 2001;Hamilton and Dolan 2001;Hamoush et al 2002].…”

“…Recently, the use of externally bonded composite materials in the form of fiber reinforced polymer (FRP) laminates and fabrics has gained widespread acceptance. The behavior of URM walls strengthened with composite materials and subjected to out-ofplane loading was examined in many experimental studies [Gilstrap and Dolan 1998;Velazquez-Dimas et al 2000;Albert et al 2001;Hamilton and Dolan 2001;Hamoush et al 2002;Kiss et al 2002;Kuzik et al 2003;Ghobarah and El Mandooh Galal 2004;Tan and Patoary 2004]. These studies reveal that the use of the externally bonded FRP system leads to an increase of 10-50 times the strength of the masonry Keywords: arching, buckling, composite materials, cracking, debonding, masonry, nonlinear analysis, strengthening, wrinkling.…”

The geometrically nonlinear effects in the out-of-plane flexural response of unreinforced masonry walls strengthened with externally bonded composite materials are analytically investigated. The investigation aims to explore the stabilizing or destabilizing influence of the arching action formed under realistic supporting conditions (restricted longitudinal deformations) of the wall, and to quantify the contribution of the strengthening system to improving the stability characteristics of the wall. The localized buckling effects associated with the development of compressive stresses in the FRP strip are also examined. Variational principles, large displacements kinematics, compatibility conditions between the structural components (masonry units, mortar joints, FRP strips, and adhesive layers), and the assumption of oneway flexural action are used for the formulation of the nonlinear analytical model. The cracking of the mortar joints, which is essential to the development of the arching action, and the formation of debonded zones are also considered. A numerical example that highlights the geometrically nonlinear effects in the response of the strengthened wall and examines the influence of the slenderness ratio is presented. The results quantify the potential increase of the limit point load and deflection due to the externally bonded composite system. They also quantitatively reveal the wrinkling phenomenon of the compressed FRP strip and the shear and peeling stress concentrations that develop in the vicinity of the cracked mortar joints, the debonded regions, and the wrinkled FRP layer. The paper closes with concluding remarks.

“…In addition, there are comprehensive researches about the out-of-plane shear behaviour of FRP-strengthened walls [22], the in-plane shear response [23] or the out-of-plane flexural response [24]. However, it is not typically analysed how these strengthening systems might affect the response and the load-bearing capacity of the walls, in particular when vertical compressive loads are applied.…”

Fibre Reinforced Polymers laminates are currently used to strengthen brick masonry walls. However, no specific evidences of the structural response of this strengthening system when brick walls are subjected to eccentric compressive loads, which might lead to second order bending effects, have been found. An experimental campaign on real-size walls has been carried out and the results have been compared with a numerical model, which predicted the observed shear/compressive masonry failure, and a new analytical approach, which has been used to accurately calculate the load-bearing capacity of the walls. Useful considerations for the strengthening design are also presented.

“…The application of externally bonded composite materials to strengthening of existing masonry walls subjected to out-of-plane loading was studied by Gilstrap and Dolan [4], Velazquez-Dimas et al [5], Albert et al [6], Hamilton and Dolan [7], Kiss et al [8], Hamoush et al [2,9], and Kuzik et al [10]. Most of the experimental and theoretical studies focused on the failure mechanisms of strengthened walls under simply supported end conditions that allow the free elongation of the wall.…”

“…Among these, the modeling of the strengthened wall as an equivalent bending member with external reinforcement was mostly used [2,7,9]. The flexural failure loads (crushing of the masonry unit or rupture of the composite material) were determined by the strain compatibility method based on the analysis of the critical section.…”
