RISExperimental Investigation and Modeling of FRP–Concrete Joint Bond Strength Based on Failure Depth
Publisher: ASCE
Abstract: The growing interest in fiber-reinforced polymer (FRP) composites in recent years for use in strengthening concrete structures bears witness to their efficiency and ease of use. A major issue in FRP strengthening designs, ...
Empirical Expression for Failure Strain in EBROG-Bonded FRP–Concrete Joints
Publisher: ASCE
Abstract: This study proposes a relation for the failure strain of externally bonded reinforcement on groove (EBROG) joints derived through multivariate regression analysis on the experimental results. In addition to the conventional ...
Theoretical Analysis of Behavior of FRP-Strengthened Reinforced Concrete Members Subjected to Combined Torsion and Biaxial Bending
Publisher: ASCE
Abstract: Reinforced concrete (RC) structural members, such as bridge girders and columns, flanged and spandrel beams, and edge frame beams, may be subjected to combined actions in the general case of loading. Despite extensive ...
Experimental Study of Circular RC Columns Strengthened with Longitudinal CFRP Composites under Eccentric Loading: Comparative Evaluation of EBR and EBROG Methods
Publisher: American Society of Civil Engineers
Abstract: Application of carbon fiber-reinforced polymer (CFRP) composites has been promoted successfully for strengthening or repairing concrete structural members. However, if a column member is strengthened with longitudinal FRP ...
Experimental Investigation of the Efficacy of EBROG Method in Seismic Rehabilitation of Deficient Reinforced Concrete Beam–Column Joints Using CFRP Sheets
Publisher: American Society of Civil Engineers
Abstract: A major cause underlying the collapse of reinforced concrete (RC) moment-resisting frames observed in past earthquakes is the shear failure of nonseismically detailed exterior beam–column joints. A number of studies have ...
Corner Strip-Batten Technique for FRP-Confinement of Square RC Columns under Eccentric Loading
Publisher: American Society of Civil Engineers
Abstract: In the present study, a new method is introduced for confining square concrete columns in which fiber-reinforced polymer (FRP) strips are used at corners and FRP battens on column sides. In this method, FRP battens confining ...
Grooving as Alternative Method of Surface Preparation to Postpone Debonding of FRP Laminates in Concrete Beams
Publisher: American Society of Civil Engineers
Abstract: Structural repair and strengthening have long been dynamic and challenging activities in construction work. One of the most commonly used methods for such repairs is the application of fiber-reinforced polymer (FRP) sheets ...
Experimental Study of Circular RC Columns Strengthened with Longitudinal CFRP Composites under Eccentric Loading: Comparative Evaluation of EBR and EBROG Methods
Publisher: American Society of Civil Engineers
Abstract: Application of carbon fiber-reinforced polymer (CFRP) composites has been promoted successfully for strengthening or repairing concrete structural members. However, if a column member is strengthened with longitudinal FRP ...
Compressive Strength of CFRP Composites Used for Strengthening of RC Columns: Comparative Evaluation of EBR and Grooving Methods
Publisher: American Society of Civil Engineers
Abstract: In the present study, application of carbon-fiber-reinforced polymer (CFRP) composites with fibers aligned along the column’s axis to improve compressive strength of reinforced concrete (RC) columns has been investigated. ...
