Discussion of “I-35W Bridge Collapse” by S. Hao
(American Society of Civil Engineers, 2011) -
Research on Cable Anchorage Systems for Self-Anchored Suspension Bridges with Steel Box Girders
(American Society of Civil Engineers, 2011)A new type of steel-concrete composite cable anchorage system is conceived and investigated preliminarily for self-anchored suspension bridges with steel box girders to optimize the mechanical behavior of the conventional ... -
Editor’s Note
(American Society of Civil Engineers, 2011) -
Experimental Study on the Performance of Approach Slabs under Deteriorating Soil Washout Conditions
(American Society of Civil Engineers, 2011)In the U.S. bridge design practice, an approach slab is commonly provided to facilitate a smooth transition from the highway pavement to the bridge deck. Maintenance of bridge approaches often necessitates the repair or ... -
Development of Flexural Strength Rating Procedures for Adjacent Prestressed Concrete Box Girder Bridges
(American Society of Civil Engineers, 2011)An investigation was conducted on noncomposite prestressed precast concrete adjacent-box-beam bridges that suffered catastrophic failures resulting from the corrosion of the prestressing steel. These failures highlight the ... -
Investigation of Bursting Forces in Anchorage Zones: Compression-Dispersion Models and Unified Design Equation
(American Society of Civil Engineers, 2011)Anchorage zones of posttensioned structures are prone to splitting cracks, necessitating rational reinforcement design methods for anticracking in such regions. This paper presents a generalized method to calculate bursting ... -
Proposed Modification of AASHTO-LRFD for Computing Stress in Unbonded Tendons at Ultimate
(American Society of Civil Engineers, 2011)In 1998, AASHTO-LRFD adopted a new equation for evaluating the stress -
Simplified Lateral Analysis of Deep Foundation Supported Bridge Bents: Driven Pile Case Studies
(American Society of Civil Engineers, 2011)A simplified approach for modeling soil and foundation system supported bridge bents is applied to three bridges that represent three pile types and three superstructures. This point-of-fixity approach is applied by modeling ... -
Fatigue Evaluation of Rib-to-Deck Welded Joints of Orthotropic Steel Bridge Deck
(American Society of Civil Engineers, 2011)This study reported fatigue test results of 300-mm-wide specimens with three details: 80% partial joint penetration (80%PJP), weld melt-through (WMT), and both. The specimens were cut out from full-scale orthotropic deck ... -
Shear Lag Analysis in Prestressed Concrete Box Girders
(American Society of Civil Engineers, 2011)Most studies on shear lag effect in box girders are only concerned about concentrated loads and uniformly distributed loads. In this paper, a finite-element method based on the variational principle is presented to analyze ... -
Discussion of “Operational Requirements for Long-Span Bridges under Strong Wind Events” by Moe M. S. Cheung and Ben Y. B. Chan
(American Society of Civil Engineers, 2012) -
Indicial Functions for Bridge Aeroelastic Forces and Time-Domain Flutter Analysis
(American Society of Civil Engineers, 2011)This paper presents a detailed numerical algorithm for time-domain flutter analysis of elongated bridges, emphasizing in particular some problematic issues with regard to the application of the indicial functions involved ... -
Redevelopment of Prestressing Force in Severed Prestressed Strands
(American Society of Civil Engineers, 2011)The flexural capacity rating of prestressed girders having severed or corroded strands often progresses by simply neglecting the contribution of the affected strands from the girder section and assessing the capacity. While ... -
Reliability-Based Dynamic Load Allowance for Capacity Rating of Prestressed Concrete Girder Bridges
(American Society of Civil Engineers, 2011)The current highway bridge design in the United States follows the AASHTO-LRFD specifications, which prescribe a dynamic load allowance, -
Flexural Testing of Precast Bridge Deck Panel Connections
(American Society of Civil Engineers, 2011)Precast deck panels are increasingly being utilized to reduce construction times and traffic delays as many departments of transportation (DOTs) emphasize accelerated bridge construction. Despite the short-term benefits, ... -
Extrapolation for Future Maximum Load Statistics
(American Society of Civil Engineers, 2011)The use of short-term load data to extrapolate or project remote future maximum load has been practiced in structural design code development and/or calibration. However, this approach has not been adequately evaluated or ... -
Bridge Rating Using System Reliability Assessment. I: Assessment and Verification by Load Testing
(American Society of Civil Engineers, 2011)Condition assessment and safety verification of existing bridges and decisions as to whether a bridge requires posting currently are addressed through analysis, load testing, or a combination of these methods. The rating ... -
Seismic Behavior of Self-Centering Precast Segmental Bridge Bents
(American Society of Civil Engineers, 2011)This paper presents the cyclic behavior of four self-centering bridge bents with different construction details, including external energy dissipaters and neoprene isolation. The columns of these bents consisted of precast ... -
Bridge Rating Using System Reliability Assessment. II: Improvements to Bridge Rating Practices

Lateral Vibration of High-Pier Bridges under Moving Vehicular Loads
(American Society of Civil Engineers, 2011)When studying the vibration of a bridge-vehicle coupled system, most researchers focus on the vertical vibration of bridges under moving vehicular loads. In reality, the moving vehicular loads can also induce significant ...
