Abstract: Three theorems of the flexural theory for RC members are derived to identify two critical points on a moment–curvature curve: (1) the onset of flexural strength and (2) the onset of the so-called true ultimate curvature. ...

Abstract: To study the stress-strain behavior of axially loaded fiber-reinforced polymer (FRP)–confined concrete columns in the event of a localized failure, 32 circular concrete cylinders were tested with heavy instrumentations. ...

Abstract: Recently, a new plating system was proposed based on a strain localization mechanism for addressing the critical debonding problem in externally bonded reinforcing systems for reinforced concrete (RC) structures. The system ...

Abstract: The interfacial bond parameters are quantified and modeled in this work through experimental and analytical studies. A database comprising 628 shear tests of externally-bonded fiber reinforced polymer (FRP) joints is built ...

Abstract: The adhesive attachment of fiber-reinforced polymers (FRP) laminate to the external face of reinforced concrete structures is currently one of the most popular and effective methods for retrofitting and strengthening ...

Abstract: Despite extensive research on externally bonded fiber-reinforced polymer (EB-FRP) for rehabilitation of concrete structures in the past two decades, the industry has been slow to embrace the technology owing to some difficult ...

Abstract: Axially-loaded concrete columns with postpeak strain-softening suffer large inelastic deformation only in a localized failure zone, leading to nonuniform deformation along the height of the columns. Therefore, calculation ...

Abstract: A new and general stress-strain model for concrete confined by steel or fiber reinforced polymer (FRP) is developed in this work. One additional variable and one constant are added to the well-known Popovics model to control ...
