Stay Force Estimation in Cable-Stayed Bridges Using Stochastic Subspace Identification Methods
(American Society of Civil Engineers, 2017)In this paper, a vibration-based approach for estimating the cable tension forces in cable-stayed bridges is detailed and applied to the ambient response of the Veterans’ Glass City Skyway Bridge. First, the frequency ... -
Load Rating of Deteriorated and FRP-Retrofitted Bridge Abutment Timber Piles
(American Society of Civil Engineers, 2017)Conventional load-rating methods for bridge timber piles consider only concentric axial loads. However, in the case of abutment piles, earth pressure and surcharge loads exert a significant lateral force on the piles. There ... -
Performance of Composite Twin I-Girder Bridges with Fatigue-Induced Cracks
(American Society of Civil Engineers, 2017)An experimental program was performed to investigate the postfracture performance of composite twin I-girder bridges in the fatigue crack condition. An intact specimen and a damaged specimen were tested under one-point ... -
Statistical Analysis of Modal Properties of a Cable-Stayed Bridge through Long-Term Wireless Structural Health Monitoring
(American Society of Civil Engineers, 2017)A dense deployment of sensors is often beneficial for obtaining a more complete understanding of the dynamic behavior of complex structures, such as long-span bridges. Wireless smart sensor networks are advantageous in ... -
Effect of Strain Hardening on the Flexural Resistance of Composite Plate Girders Using HSB600 High-Performance Steel in Positive Bending
(American Society of Civil Engineers, 2017)This study presents a new nominal flexural resistance of composite I-girder sections using high-performance steel, HSB600, in the positive bending region. Unlike conventional steels, HSB600 undergoes strain hardening ... -
Simplified System-Level Pavement-Stiffness Model for Box Culvert Load-Rating Applications
(American Society of Civil Engineers, 2017)Tens of thousands of aging, bridge-class, RC box culverts are in service in the United States. Within the context of establishing load rating for in-service RC box culverts, this paper introduces, calibrates, and applies ... -
Fatigue Life Evaluation on Short Suspenders of Long-Span Suspension Bridge with Central Clamps
(American Society of Civil Engineers, 2017)Suspenders are crucial load-bearing members of suspension bridges, and they are prone to fatigue damage under repetitive vehicle and wind loads. Field observation shows that short suspenders at the midspan or the ends of ... -
Fatigue Performance of Rib-to-Deck Joints in Orthotropic Steel Decks with Thickened Edge U-Ribs
(American Society of Civil Engineers, 2017)This study evaluated the fatigue performance of rib-to-deck welded joints in orthotropic steel decks (OSDs) with thickened edge U-ribs (TEUs). Fatigue performance of four rib-to-deck specimens with TEUs was investigated ... -
Load-Capacity Rating of Bridge Populations through Machine Learning: Application of Decision Trees and Random Forests
(American Society of Civil Engineers, 2017)The functionality of the U.S. transportation infrastructure system is dependent upon the health of an aging network of over 600,000 bridges, and agencies responsible for maintaining these bridges rely on the process of ... -
Experimental Study of the Aseismic Effect of a Locking Ball for a Continuous Bridge
(American Society of Civil Engineers, 2017)Current sliding-bearing designs do not make full use of the stiffness and potential ability of sliding piers in the aseismic design of continuous bridges. Aiming at the problem that the demand on the only fixed-pier force ... -
Live Load Distribution Factors for Spread Slab Beam Bridges
(American Society of Civil Engineers, 2017)The design and construction of spread slab beam bridges is becoming commonplace in Texas. Although this relatively new class of bridge is somewhat similar to spread box beam bridges, it is unclear whether the existing live ... -
Field Test of a Large-Span Soil–Steel Bridge Stiffened by Concrete Rings during Backfilling
(American Society of Civil Engineers, 2017)In this article, a field test of a large-span soil–steel bridge is described. The case study involved a corrugated steel plate that was stiffened by concrete rings. The rings were applied to make it possible to use only ... -
Coupled Fatigue-Corrosion Failure Analysis and Performance Assessment of RC Bridge Deck Slabs
(American Society of Civil Engineers, 2017)Coupled fatigue and corrosion is more detrimental for RC bridge deck slabs than either fatigue or corrosion separately. The main objectives of this study are to obtain a greater understanding of the deterioration mechanisms ... -
Testing and Analysis of Precast Columns with Grouted Sleeve Connections and Shifted Plastic Hinging
(American Society of Civil Engineers, 2017)Prefabricated reinforced concrete column connections employing grouted sleeve (GS) splices enable rapid construction, are familiar to contractors, and their detailing resembles cast-in-place (CIP) construction. Previous ... -
Performance of FRCM-Strengthened RC Beams Subject to Fatigue
(American Society of Civil Engineers, 2017)Fabric-reinforced cementitious matrix (FRCM) is a relatively new material system developed for the repair, retrofit, and rehabilitation of reinforced concrete (RC) and masonry structures. Structures such as bridges experience ... -
Real-Time Reference-Free Displacement of Railroad Bridges during Train-Crossing Events
(American Society of Civil Engineers, 2017)Today, railroads carry 40% of the United States’ freight tonnage, and the demand for this service is expected to double in 20 years. The railroad infrastructure contains more than 100,000 bridges spanning over 225,000 km ... -
