RISSeismic Repair of Reinforced Concrete Bridge Columns: Review of Research Findings
Publisher: American Society of Civil Engineers
Abstract: Repair has become a viable option for restoring the use of earthquake-damaged RC elements, even those that have been severely damaged. To select and design an appropriate repair system for damaged RC bridge columns, it is ...
Role of the Matrix Layers in the Stress-Transfer Mechanism of FRCM Composites Bonded to a Concrete Substrate
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced cementitious matrix (FRCM) composites represent a newly developed promising technique for strengthening RC structures. The FRCM composites are comprised of high-strength fibers applied to the concrete ...
Simulation-Based Models for Postearthquake Response: A Survey and Research Directions
Publisher: American Society of Civil Engineers
Abstract: Computer simulation is increasingly being used by emergency planners as a tool to improve disaster response given that it can model real-world scenarios, such as earthquakes. Although there has been an increase in simulation ...
Shear Strength Model for Reinforced Concrete Beams with U-Wrapped FRCM Composites Based on the Critical Shear Crack Width Evolution
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new procedure to determine the different shear strength contributions of RC beams strengthened with U-wrapped externally bonded (EB) fiber-reinforced cementitious matrix (FRCM) composites. A main shear ...

Numerical Simulation of Partial-Depth Precast Concrete Bridge Deck Spalling
Publisher: American Society of Civil Engineers
Abstract: This paper describes the results of numerical simulations performed to investigate the spalling mechanism observed in several partial-depth precast prestressed concrete (PPC) bridge decks. Corrosion-induced cracking of ...
Three-Dimensional Numerical Modeling of Single-Lap Direct Shear Tests of FRCM-Concrete Joints Using a Cohesive Damaged Contact Approach
Publisher: American Society of Civil Engineers
Abstract: The bond behavior of fiber-reinforced cementitious matrix (FRCM) composites applied as externally bonded reinforcement is the most critical concern in this type of application. FRCM–concrete joints are generally reported ...
Shear Strength Model for RC Beams with U-Wrapped FRCM Composites
Publisher: ASCE
Abstract: The shear strength of reinforced concrete (RC) elements can be improved by applying externally bonded (EB) fiber-reinforced cementitious matrix (FRCM) composites. FRCM composites are generally U-wrapped around the cross-section ...
Analytical Study on the Torsional Behavior of Reinforced Concrete Beams Strengthened with FRCM Composite
Publisher: American Society of Civil Engineers
Abstract: In this study, an analytical approach was used to predict the full torsional response of RC beams strengthened with externally bonded fiber-reinforced cementitious matrix (FRCM) composite. The analytical model was based ...
Compressive Behavior of Brick Masonry Columns Confined with Steel-Reinforced Grout Jackets
Publisher: American Society of Civil Engineers
Abstract: In this study, a new type of composite comprised of steel cords embedded in a mortar matrix—referred to as steel-reinforced grout (SRG)—is explored for use in the confinement of masonry columns. This paper presents the ...
