RISBeyond the Mean: Long-Term Variabilities in Precipitation and Temperature on the Qinghai–Tibetan Plateau
Publisher: American Meteorological Society
Efficient Pavement Damage Detection Algorithm Based on Lightweight Feature Enhancement Network
Publisher: American Society of Civil Engineers
Abstract: AbstractEfficient detection of pavement damage in complex natural environments is crucial
for intelligent maintenance of transportation infrastructure. To address challenges
related to structural complexity, resource ...
Experimental Evaluation of Fire Resistance and Postfire Mechanical Behavior of Cables with Multiple Fire Protection Strategies
Publisher: American Society of Civil Engineers
Abstract: Abstract As critical components of cable-supported bridges, bridge cables face significant
threats from elevated temperatures induced by fire accidents. This study developed
a specialized fire-furnace test to evaluate the ...
Damage Mechanism of Control Springs in Modular Expansion Joints of Long-Span Bridges
Publisher: American Society of Civil Engineers
Abstract: Premature damage in modular expansion joints, especially in control springs, has been observed in several long-span bridges, which calls for an in-depth study on the damage mechanism. In this study, relative movements of ...
Fatigue Performance of Rib-to-Deck Joints Strengthened with FRP Angles
Publisher: American Society of Civil Engineers
Abstract: Rib-to-deck joints of orthotropic steel decks (OSDs) in steel bridges are susceptible to longitudinal fatigue cracking, which often results in considerable repair costs as well as traffic interruption. To mitigate such ...
Corrosion Fatigue Analysis and Reliability Assessment of Short Suspenders in Suspension and Arch Bridges
Publisher: American Society of Civil Engineers
Abstract: Suspenders are critical force transmission components in suspension and arch bridges, which connect the girder to the main cable/arch. Field inspection indicates that short suspenders at the midspan or the ends of a bridge ...
Long-Term Performance and Durability Assessment of FRP-Strengthened Rib-to-Deck Welds in Orthotropic Steel Bridges: Six-Year Field Monitoring Study
Publisher: American Society of Civil Engineers
Abstract: AbstractThis study investigated the long-term fatigue performance of rib-to-deck welds in
the Runyang Suspension Bridge (RSB)’s orthotropic steel deck (OSD), strengthened with
L-shaped fiber-reinforced polymer (L-FRP) ...
Seismic Performance Assessment of Self-Centering Tall Piers: Cyclic Loading Test and Numerical Analysis
Publisher: American Society of Civil Engineers
Abstract: Abstract This paper introduces the cyclic loading test and numerical model of a novel self-centering
(SC) tall pier. This tall pier system is connected to the girder and foundation, respectively,
through pre-embedded ...
Seismic Performance of Hybrid Self-Centering Braces with Structural and Nonstructural Damage Control Functions: Validation Tests, Computational Modeling, and Benefits Evaluation
Publisher: American Society of Civil Engineers
Abstract: AbstractThis paper presents a comprehensive study of validation tests, computational modeling,
and system-level benefits evaluation of an innovative hybrid self-centering brace
(HSB) with structural and nonstructural damage ...
Error-Diminished Model of Crack Growth Test for Corrosion Fatigue of Base Steels and Welds Using Knowledge–Data Conjoint Analysis
Publisher: American Society of Civil Engineers
Abstract: AbstractThe strong corrosive environment and cyclic dynamic load represented by marine scenarios
put forward higher requirements for the corrosion-fatigue performance and crack resistance
of high-strength steel structures. ...
