Effect of shear deformation on adhesive stresses in plated concrete beams: Analytical solutions

Analytical and numerical solution of the interfacial stress in reinforced-concrete beams reinforced with bonded prestressed composite plate

“…[1][2][3] In recent applications, the use of prestressed laminates has been explored both in laboratory tests 4,5 and in field applications on bridges 6 and other types of structures. 7,8 By prestressing the laminate, the ultra high tensile strength of the composite material can be better utilized, which gives a more effective strengthening scheme. Furthermore, the strengthening effect obtained when prestressed laminates are employed will not only be limited to additional imposed loads on the strengthened structure, but will also participate in carrying a portion of the dead load.…”

“…Analysis of interfacial stress in beams with bonded plates has been performed by several researchers, [9][10][11][12][13][14][15][16][17][18][19] Touati et al, 8 and Belakhdar et al 20 The analyses provided closed-form formulas for the calculation of interfacial shear and peeling stress in beams with bonded non-prestressed plates or laminates. However, the problem of interfacial stress when prestressed laminates are used in strengthening, and repair has treated only by Al-Emrani 21 and Benachour et al 22,23 In this investigation, only interfacial shear stress was studied, and the analyzed beam was not loaded.…”
