RISInnovative CFRP-Prestressing System for Strengthening Metallic Structures
Publisher: American Society of Civil Engineers
Abstract: An innovative retrofit system to prestress carbon fiber reinforced polymer (CFRP) plates and attach them to existing metallic beams was developed (patent number CH 706 630 B1) and tested. The system does not require any ...
Development of Mechanical Strengthening System for Bridge Connections Using Prestressed CFRP Rods
Publisher: ASCE
Abstract: Stringer-to-floor beam web-to-web double-angle connections are among the most fatigue-prone elements in old riveted bridges. These connections are often designed to carry only shear loads. However, in these elements, fatigue ...
Strengthening of Steel Connections in a 92-Year-Old Railway Bridge Using Prestressed CFRP Rods: Multiaxial Fatigue Design Criterion
Publisher: ASCE
Abstract: This paper presented a new retrofit system for strengthening the stringer-to-floor-beam double-angle connections in a 92-year-old riveted railway bridge in Switzerland, using prestressed carbon fiber-reinforced polymer ...
Development of a Mechanical Wedge–Barrel Anchor for CFRP Rods: Static and Fatigue Behaviors
Publisher: ASCE
Abstract: In this study, a mechanical anchorage for prestressed carbon fiber–reinforced polymer (CFRP) rods was proposed. The proposed anchorage consisted of a steel barrel with a conical hole and three separate aluminum wedges that ...
Heat Activated SMA-CFRP Composites for Fatigue Strengthening of Cracked Steel Plates
Publisher: ASCE
Abstract: Many studies exist on carbon fiber-reinforced polymer (CFRP) strengthening of cracked steel details (e.g., cracks in riveted or welded bridge connections). The majority of these studies used CFRP sheets without prestressing. ...
