Investigating the Mechanical Properties and Fracture Behavior of Welded-Wire Reinforcement
Publisher: ASCE
Abstract: Welded-wire reinforcement (WWR) is widely used as the main reinforcement in bridge decks and vertical shear reinforcement in concrete bridge girders. Previous studies on concrete members reinforced with WWR have indicated ...
Fatigue Performance of Overhead Truss Sign Structure Coupler Connections
Publisher: ASCE
Abstract: Nearly all aluminum overhead truss sign structures (OHTSSs) in Kansas constructed before 2015 use an identical type of hot-riveted coupling assembly to provide connections between vertical poles and horizontal truss members. ...
Fatigue Performance of Saddle Connections in Aluminum Overhead Truss Sign Structures
Publisher: ASCE
Abstract: A newly developed saddle-type connection has been adopted for use at the joints of support-frame poles and truss chords in aluminum overhead truss sign structures (OHTSS) in Kansas since 2015. This paper describes a study ...
State-of-the-Art Fracture Characterization. II: Correlations between Charpy V-Notch and the Master Curve Reference Temperature
Publisher: American Society of Civil Engineers
Abstract: Many material toughness specifications, including a fracture control plan (FCP) for highway bridges introduced in 1978, in part rely on Charpy V-notch (CVN) requirements and associated correlations to set material toughness ...
Fracture Toughness Characterization of High-Performance Steel for Bridge Girder Applications
Publisher: American Society of Civil Engineers
Abstract: The use of high-performance steel (HPS) in new bridge construction continues to increase as engineers and owners recognize the potential for cost savings and performance benefits. One intended advantage of HPS is the ...
State-of-the-Art Fracture Characterization. I: Master Curve Analysis of Legacy Bridge Steels
Publisher: American Society of Civil Engineers
Abstract: Advances in the field of fracture mechanics over the last four decades have allowed for a greater understanding of brittle and ductile fracture, including how to account for plasticity in fracture specimens and how to ...
Thin-Film Sensor for Fatigue Crack Sensing and Monitoring in Steel Bridges under Varying Crack Propagation Rates and Random Traffic Loads
Publisher: American Society of Civil Engineers
Abstract: Fatigue cracks are critical structural concerns for steel highway bridges, and fatigue initiation and propagation activity continues undetected between physical bridge inspections. Monitoring fatigue crack activity between ...
Development of a Distortion-Induced Fatigue Crack Characterization Methodology Using Digital Image Correlation
Publisher: ASCE
Abstract: Distortion-induced fatigue cracking is a primary maintenance and structural safety concern in steel bridges built prior to the 1980s in the United States. Manual, hands-on inspections are currently the primary method ...
