Fiber-Reinforced Polymer for Structural Strengthening: Post-Tensioning of Steel Silos

Analysis of interfacial shear stresses in beams strengthened with bonded prestressed laminates

“…These materials, often in laminate form, have been successfully used in strengthening existing concrete, masonry, timber and lately steel structures. In recent applications, the use of prestressed laminates has been explored both in laboratory tests [1,2] and in field applications on bridges [3] and other types of structures [4]. By prestressing the laminate, the ultra high tensile strength of the composite material can be utilized better, which gives a more effective strengthening scheme.…”

Improved Stresses Analysis of a Functionally Graded Beam under Prestressed CFRP Plate

“…oulli beam theory, the axial force N and bending moment resultants M are (5) from equations (3) and (4) into equation (5), a relation between the force tants and the beam deformations can be derived as follows in equation 6:…”

“…beam stiffness coefficients A, B and D are: By substituting σ x from equations (3) and (4) into equation (5), a relation between the force and moment resultants and the beam deformations can be derived as follows in equation 6:…”

Interfacial stress analysis of steel beams reinforced with bonded prestressed FRP plate

“…In recent applications, the use of prestressed laminates has been explored both in laboratory tests [11,12] and in field applications on bridges [13] and other types of structure [14]. By prestressing the laminate, the ultra high tensile strength of the composite material can be better utilized, which gives a more effective strengthening scheme.…”
