RISEffect of FRP Spike Anchor Installation Quality and Concrete Repair on the Seismic Behavior of FRP-Strengthened RC Columns
Publisher: ASCE
Abstract: The use of fiber-reinforced polymer (FRP) to repair and seismically strengthen existing deficient or damaged structural elements is now widespread. FRP anchors have become an important component of such FRP strengthening. ...
Seismic Strengthening of the Mohaka Township Concrete Bridge with FRP Fabric and FRP Spike Anchors: Case Study in New Zealand
Publisher: ASCE
Abstract: The Mohaka Township, New Zealand, reinforced concrete bridge was designed in 1958, measuring 239 m long and divided into 14 spans, each 17.1 m long. The piers are doubly reinforced concrete walls over a pile cap with 12 ...
Axial Behavior of Concrete Prisms Confined by FRP Laminate and Spike Anchors
Publisher: ASCE
Abstract: Reinforced concrete (RC) buildings constructed before introducing ductile design requirements may exhibit undesirable seismic behavior. One such vulnerability is the lack of confinement to end regions that may lead to ...
Prevention of Brittle Axial Failure of Lightly Reinforced Concrete Walls Retrofitted with FRP Laminate and Anchors
Publisher: American Society of Civil Engineers
Abstract: This study investigates a novel retrofitting technique to prevent premature axial failure and collapse of RC walls during earthquakes, attributed to inadequate compressive strain capacity in boundary regions. The technique ...
FRP Tension Ties: State-of-the-Art Review of Existing Design Guidance for Debonding Capacity and Applicability to Concrete Diaphragm Seismic Strengthening
Publisher: ASCE
Abstract: Fiber-reinforced polymer (FRP) ties can be used to provide tensile capacity to seismic-deficient concrete diaphragms, but there are no existing research or design provisions and guidance on how to design such ties is ...
An Experimental Study of the Behavior of GFRP-Reinforced Precast Concrete Culverts
Publisher: ASCE
Abstract: This paper presents the results of an experimental study carried out to evaluate the structural behavior of precast concrete culverts reinforced with glass fiber–reinforced polymer (GFRP) bars. Five full-scale GFRP reinforced ...
