Cracking of Longitudinal Diaphragms in Long-Span Cable-Stayed Bridges
(American Society of Civil Engineers, 2015)Longitudinal diaphragms are frequently used in steel box girders of long-span cable-stayed bridges to obtain desirable performance of steel girders. Field examination, however, reveals that premature cracking may often ... -
Reference-Free Displacements for Condition Assessment of Timber Railroad Bridges
(American Society of Civil Engineers, 2016)Current railroad bridge inspection and rating practices include observing bridge movement under live loads to help assess bridge conditions. Recent research has shown that transverse displacements of timber trestle bridges ... -
Experimental Characterization of Ultrahigh-Performance Concrete Bridge Deck System
(American Society of Civil Engineers, 2015)A lightweight, low-profile ultrahigh-performance concrete (UHPC) deck system reinforced with high-strength steel (HSS) has been proposed by the authors as an alternative to open grid steel deck. The system consists of a ... -
Estimation of Cascadia Local Tsunami Loads on Pacific Northwest Bridge Superstructures
(American Society of Civil Engineers, 2016)The time histories of Cascadia Subduction Zone (CSZ) local tsunami horizontal and vertical loads and the overturning moment on four selected Oregon coastal bridges are computed for different load scenarios. These scenarios, ... -
Extraction of Bridge Frequencies from a Moving Test Vehicle by Stochastic Subspace Identification
(American Society of Civil Engineers, 2016)The technique for extracting bridge frequencies from a moving vehicle was proposed only recently. However, its efficacy may be reduced by road-surface roughness. To this end, the stochastic subspace identification (SSI) ... -
Evaluation of Torsional Vibrations in Steel Truss Bridge Members
(American Society of Civil Engineers, 2015)Long and torsionally slender H-shaped cross sections, often used as tension members in truss bridges, can exhibit wind-induced torsional motions. These motions have produced high-cycle fatigue damage for some bridges. There ... -
Evaluation of Cracks in a Large Single-Cell Precast Concrete Segmental Box Girder Bridge without Internal Struts
(American Society of Civil Engineers, 2015)The Hathaway Bridge, an eastbound and westbound bridge pair, is located in Panama City, Florida. Each of the pair consists of a single-box precast concrete segmental girder with a deck width of 24.4 m (80 ft). The lengths ... -
Cyclic Loading Test of Unbonded and Bonded Posttensioned Precast Segmental Bridge Columns with Circular Section
(American Society of Civil Engineers, 2016)Four -
Vehicle-Induced Lateral Vibration of Railway Bridges: An Analytical-Solution Approach
(American Society of Civil Engineers, 2016)The lateral vibration of railway bridges induced by moving trains has traditionally been solved through numerical integration. Although it provides practical prediction, the numerical approach does not explicitly reveal ... -
Cost-Efficient Procurement of Bridge Infrastructures by Incorporating Life-Cycle Cost Analysis with Bridge Management Systems
(American Society of Civil Engineers, 2015)Life-cycle cost analysis (LCCA) has recognized potential for rationalizing bridge procurement, but its use in this context is far from systematic. The integration of LCCA findings in decisions is often far from robust. ... -
Reliability Assessment of Tie-Down Cables for Cable-Stayed Bridges Subject to Negative Reactions: Case Study
(American Society of Civil Engineers, 2015)This paper presents a reliability assessment for tie-down cables of cable-stayed bridges subject to negative reactions. The advanced first-order second-moment reliability method (AFOSM) is used to evaluate the reliability ... -
Structural Behavior of Barges in High-Energy Collisions against Bridge Piers
(American Society of Civil Engineers, 2016)The collision of barges against bridge piers is an extreme loading condition that usually governs the design of bridges that span navigable waterways. The magnitude and time variation of impact forces depend on several ... -
Effects of Bridge Accessories in Steel–Concrete Composite Railway Bridges in Service Condition
(American Society of Civil Engineers, 2016)Bridge accessories, such as parapets, service ducts, and track slabs, are commonly used in railway bridges, but their real effects on the structural behavior of the bridges are still unknown because very few studies have ... -
Shake Table Studies of Seismic Structural Systems of a Taizhou Changjiang Highway Bridge Model
(American Society of Civil Engineers, 2015)Taizhou Changjiang Highway Bridge is the longest three-pylon two-span suspension bridge in the world. To investigate the seismic performance of different connecting configurations between the deck and pylons, which are ... -
Corrosion Activity in Precast Concrete Elements and Cementitious Closure Pours
(American Society of Civil Engineers, 2015)The use of precast concrete elements in the construction of highway bridges has been a common practice in the United States since the 1950s. These bridges have generally performed well during the initial years after ... -
Inhibiting Distortion-Induced Fatigue Damage in Steel Girders by Using FRP Angles
(American Society of Civil Engineers, 2015)The idea of retrofitting web stiffener ends in steel bridge girders susceptible to distortion-induced fatigue using adhesively bonded fiber-reinforced polymer (FRP) angles is introduced in this study. The proposed retrofit ... -
Effect on Bridge Load Effects of Vehicle Transverse In-Lane Position: A Case Study
(American Society of Civil Engineers, 2015)This paper presents an investigation of the influence of vehicle transverse in-lane position on bridge traffic load effects. To analyze the influence, both finite-element analysis and statistical analysis methods are used, ... -
Response-Spectrum Analysis for Barge Impacts on Bridge Structures
(American Society of Civil Engineers, 2015)Bridge structures that span navigable waterways are inherently at risk for barge collision incidents and therefore must be designed for impact loading. Current U.S. barge impact analysis procedures consist primarily of ... -
Improvement of Aerodynamic Performance and Energy Supply of Bridges Using Small Wind Turbines
(American Society of Civil Engineers, 2015)This study proposes a methodology of using small wind turbines for dual purposes, improving the aerodynamic performance of flexible bridges and wind-energy harvesting. A method for the proper placement of small wind turbines ... -
Experimental and Analytical Study of High-Level Barge Deformation for Barge–Bridge Collision Design
(American Society of Civil Engineers, 2016)Specifications used in the design of bridges that cross barge-navigable waterways typically use, as a subcomponent of the impact-load calculation process, a barge force–deformation (crush) relationship. Such relationships ...
