Sliding Resistance of Main Cables in Double-Cable Multispan Suspension Bridges
(American Society of Civil Engineers, 2017)Sliding resistance of the main cable is of the biggest concern when designing multispan suspension bridges. This paper presents a study on the layout form and sliding-resistance stability of the main cable in a double-cable ... -
Evaluation of Transverse Tie Rods in a 50-Year-Old Adjacent Prestressed Concrete Box Beam Bridge
(American Society of Civil Engineers, 2017)Adjacent prestressed concrete box beam bridges are one of the most popular bridges in the United States for short to medium spans. Recently, there has been concern about the structural capacity of these bridges as they age ... -
A Practical Approach for Generating the Strut-and-Tie Models of Anchorage Zones
(American Society of Civil Engineers, 2017)This paper presents a practical method for automatically generating optimal strut-and-tie models (STMs) in anchorage zones. In the proposed approach, a new microtruss element pattern is created to build ground structures. ... -
Analysis of Fiber-Optic Strain-Monitoring Data from a Prestressed Concrete Bridge
(American Society of Civil Engineers, 2017)This paper presents data from fiber-optic strain monitoring of the Nine Wells Bridge, which is a three-span, pretensioned, prestressed concrete beam-and-slab bridge located in Cambridgeshire in the United Kingdom. The ... -
Laboratory Evaluation of Ultrahigh-Performance Concrete Shear Key for Prestressed Adjacent Precast Concrete Box Girder Bridges
(American Society of Civil Engineers, 2017)Precast adjacent box girder bridges have become a preferred solution in several states due to their simple structure, economy, and ease of construction. However, longitudinal cracks often appear along the shear keys between ... -
Time-Dependent Analysis of Posttensioned Bridge Hinge Curl
(American Society of Civil Engineers, 2017)Accurate prediction of instantaneous and time-dependent deformation of superstructure in-span hinges is important for preventing a mismatch of bridge decks. Time-dependent deflection of in-span hinges hinge curl in ... -
Stress Increase of Unbonded Tendons in Continuous Posttensioned Members
(American Society of Civil Engineers, 2017)A database of 253 unbonded tendon-reinforced members was assembled and analyzed with a focus on Δfps. Large scatter was observed and gaps were identified in previous databases due to possibly unsuitable inclusion of certain ... -
Flexural Resistance of Longitudinally Stiffened I-Girders. I: Yield Limit State
(American Society of Civil Engineers, 2017)The current AASHTO specification requirements for the web bend-buckling strength-reduction factor (Rb) do not consider the influence of longitudinal stiffeners on the flexural resistance of steel I-girders subsequent to ... -
Seismic Capacity Evaluation of Exterior Shear Keys of Highway Bridges
(American Society of Civil Engineers, 2017)Shear keys as sacrificial components are widely used in cap beams and abutments of highway bridges to limit the transverse displacement of superstructures and avoid damage of substructures. To investigate the seismic ... -
Evaluation of Design Guidelines for the Serviceability Assessment of Aluminum Pedestrian Bridges
(American Society of Civil Engineers, 2017)Serviceability issues related to lightweight pedestrian bridges have attracted a great deal of attention in the literature since the London Millennium Bridge incident, which involved large amplitude motions during its ... -
End-Warping Bracings during the Construction of Steel Bridges
(American Society of Civil Engineers, 2016)Slight bracing of steel bridges to control end warping of the compression flanges near the end supports can be very effective in enhancing the load-carrying capacity of the main girders that are involved. Relatively little ... -
Lateral Isolation System of a Long-Span Cable-Stayed Bridge with Heavyweight Concrete Girder in a High Seismic Region
(American Society of Civil Engineers, 2017)This paper primarily introduces a new lateral isolation system proposed for the seismic control of a long-span cable-stayed bridge, namely, the Yongning Yellow River Bridge, with high seismic activity and a heavyweight ... -
Rigid-Body Motion of Horizontally Curved Bridges Subjected to Earthquake-Induced Pounding
(American Society of Civil Engineers, 2016)Horizontally curved bridges have been observed to suffer severe structural damage during past earthquakes. Unseating of the deck from abutments is one of the typical modes of failure of horizontal curved bridges. This type ... -
Failure Analysis of a Girder Bridge Collapse under Eccentric Heavy Vehicles
(American Society of Civil Engineers, 2016)In recent years, several accidental collapses of girder bridges have occurred under the influence of eccentric heavy vehicles in China. To explore the causes and mechanisms of the collapses, a collapsed six-span, RC, ... -
State-of-the-Art Fracture Characterization. II: Correlations between Charpy V-Notch and the Master Curve Reference Temperature
(American Society of Civil Engineers, 2016)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 ... -
Predicting the Bounds of Vehicle-Induced Bridge Responses Using the Interval Analysis Method
(American Society of Civil Engineers, 2016)A method for predicting the bounds of vehicle-induced bridge responses with uncertain bridge and vehicle parameters is presented. The uncertainties in the parameters of the bridge and vehicle are represented with interval ... -
Collapse Failure of Prestressed Concrete Continuous Rigid-Frame Bridge under Strong Earthquake Excitation: Testing and Simulation
