Quality Assurance of Measured Response Intended for Fatigue Life Prediction
(American Society of Civil Engineers, 2012)By in situ measurements, the real distribution of stress ranges caused by service loads can be recorded. Inherent effects in the measured response as disturbance can, however, create puzzles in the interpretation of the ... -
Sensor Networks, Computer Imaging, and Unit Influence Lines for Structural Health Monitoring: Case Study for Bridge Load Rating
(American Society of Civil Engineers, 2012)In this paper, a novel methodology for structural health monitoring of a bridge is presented with implementations for bridge load rating using sensor and video image data from operating traffic. With this methodology, video ... -
Practical Approach for Estimating Distribution Factor for Load Rating: Demonstration on Reinforced Concrete T-Beam Bridges
(American Society of Civil Engineers, 2012)This paper presents a new, practical methodology with simple analysis methods coupled with rapid experimental tests to identify distribution factors (DFs) for existing highway bridges. This approach is demonstrated on a ... -
Code Formulas for Ship-Impact Design of Bridges
(American Society of Civil Engineers, 2012)Four finite-element models of ships with deadweight tonnage varying from 3,000 to 50,000 t are developed for numerical collision simulation. The time histories of ship collisions against rigid walls are obtained using the ... -
Blast Resistance of Steel Orthotropic Bridge Decks
(American Society of Civil Engineers, 2012)The main objectives of this study were to: (1) study the response of bridge decks to blast effects resulting from an explosion on the deck; and (2) develop efficient technologies and systems that can be used in design and ... -
Seismic Fragility of Retrofitted Multispan Continuous Steel Bridges in New York
(American Society of Civil Engineers, 2012)Various retrofit measures, such as elastomeric bearings, lead-rubber bearings, viscous dampers, and jacketing with carbon fibers, are commonly used to improve the seismic performance of multispan continuous steel highway ... -

Treatment of <i>P</i>-Δ Effects in Displacement-Based Seismic Design for SDOF Systems
(American Society of Civil Engineers, 2012)The displacement-based seismic-design (DSD) methods, owing to their simplicity and efficiency, have been more and more recognized in structural seismic-research communities during the past few years. However, the dynamic -
Influence of Skew Angle on Continuous Composite Girder Bridge
(American Society of Civil Engineers, 2012)The design of skewed bridges is becoming more customary in the engineering community. In this paper, the effect of the skew angle on continuous composite girder bridges is presented using three-dimensional finite-element ... -

Statistical Distribution of Bridge Resistance Using Updated Material Parameters
(American Society of Civil Engineers, 2012)Resistance (load-carrying capacity) of a bridge girder is a random variable and can be determined by considering the uncertainty in material, fabrication, and professional/analysis properties. Previous calibrations of load ... -
Fatigue Performance of High-Strength Reinforcing Steel
(American Society of Civil Engineers, 2012)An evaluation of concrete reinforcing bar fatigue provisions of AASHTO -
Structural Behavior of Inferior-Deck Spatial Arch Bridges with Imposed Curvature
(American Society of Civil Engineers, 2012)Spatial arch bridges have significant out-of-plane behavior that must be controlled even under vertical loads. In some designs, the centerline of the arch may not lie within a plane. This study focuses on the structural ... -
Investigation of Extreme Environmental Conditions and Design Thermal Gradients during Construction for Prestressed Concrete Bridge Girders
(American Society of Civil Engineers, 2012)Current AASHTO specifications provide engineers with a temperature gradient across the depth of the cross section to predict the vertical thermal behavior of bridges. This gradient is based on one-dimensional heat flow and ... -
Advanced Numerical Modeling of Cracked Tubular K Joints: BEM and FEM Comparison
(American Society of Civil Engineers, 2012)A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. The estimation of a fatigue crack life using the linear elastic fracture mechanics (LEFM) theory involves the calculation ... -
Buckling Behavior of Steel Bridge I-Girders Braced by Permanent Metal Deck Forms
(American Society of Civil Engineers, 2012)Permanent metal deck forms (PMDFs) are often used in the bridge industry to support wet concrete and other loads during construction. Although metal formwork in the building industry is routinely relied on for stability ... -
Simplified Method for Evaluating the Redundancy of Twin Steel Box-Girder Bridges
(American Society of Civil Engineers, 2012)A fracture-critical bridge (FCB) is a structure that is expected to collapse after the failure of an essential tension component. In the positive bending moment region, the bottom flanges of a twin steel box-girder bridge ... -
Moment and Shear Load Distribution Factors for Multigirder Bridges Subjected to Overloads
(American Society of Civil Engineers, 2012)Movement of industrial freight infrequently requires special overload vehicles weighing 5 to 6 times the normal legal truck weights. The gross vehicle weight of the vehicles frequently exceeds 1800 kN whereas, the normal ... -
Dynamic Analysis of Multihazard-Resistant Bridge Piers Having Concrete-Filled Steel Tube under Blast Loading
(American Society of Civil Engineers, 2012)Research was conducted to analytically investigate the blast-response and behavior of multihazard-resistant bridge piers having circular-shaped, concrete-filled steel tube (CFST) columns. Two different analysis methods, ...
