RISAssessment of Bridge Remaining Fatigue Life through Field Strain Measurement
Publisher: American Society of Civil Engineers
Abstract: With the aging of existing steel bridges and the accumulated stress cycles under traffic loads, assessment of remaining fatigue life for continuing service has become more important than ever, especially for decisions on ...
Investigation of Large Web Fractures of Welded Steel Plate Girder Bridge
Publisher: American Society of Civil Engineers
Abstract: Constructed in 1972 with ASTM A36 (250 MPa) steel, a highway bridge in Maryland is comprised of seven welded steel plate girders of a constant web depth of 2,286 mm (90 in.). In March 2003, the web fractures of two steel ...
Investigation and Retrofit of Distortion-Induced Fatigue Cracks in a Double-Deck Cantilever-Suspended Steel Truss Bridge
Publisher: American Society of Civil Engineers
Bilinear S-N Curves and Equivalent Stress Ranges for Fatigue Life Estimation
Publisher: American Society of Civil Engineers
Abstract: With the magnitude of some stress cycles in a live load stress range spectrum being higher than the constant amplitude fatigue limit (CAFL) of a structural detail, the development of a fatigue crack could be expected. The ...
Behavior and Fatigue Performance of Details in an Orthotropic Steel Bridge with UHPC-Deck Plate Composite System under In-Service Traffic Flows
Publisher: American Society of Civil Engineers
Abstract: Using field monitoring and finite-element analysis (FEA), this paper presents the results of an investigation on stress behavior and fatigue life estimation of fatigue-prone details on an orthotropic steel deck (OSD) with ...
