RISRepairing Distortion-Induced Fatigue Cracks in Steel Bridge Girders Using Angles-with-Plate Retrofit Technique. I: Physical Simulations
Publisher: American Society of Civil Engineers
Abstract: Physical simulations of 914 mm (36 in.) deep girder-cross frame subassemblies subjected to cyclic loading were carried out to study the effects of distortion-induced fatigue and to evaluate the effectiveness of a new ...
Repairing Distortion-Induced Fatigue Cracks in Steel Bridge Girders Using Angles-with-Plate Retrofit Technique. II: Computer Simulations
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results from computer simulations of 914 mm (36 in.) deep girder-cross frame subassemblies to study the effects of distortion-induced fatigue and to evaluate the effectiveness of a newly proposed ...
Use of CFRP Overlays to Repair Fatigue Damage in Steel Plates under Tension Loading
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced polymer (FRP) overlays have been successfully used in the aerospace industry to repair fatigue damage in aluminum plates. With this success there is potential for use of similar FRP overlays to repair ...
Fatigue Enhancement of Welded Details in Steel Bridges Using CFRP Overlay Elements
Publisher: American Society of Civil Engineers
Abstract: Carbon-fiber reinforced polymer (CFRP)-overlay elements were developed with the purpose of enhancing the fatigue performance of welded connections in steel bridge girders. Fatigue tests of seven specimens, including four ...
