Calibration of Live-Load Factor in LRFD Bridge Design Specifications Based on State-Specific Traffic Environments
(American Society of Civil Engineers, 2011)In this paper, the live load factor in the Strength I Limit State in the AASHTO LRFD Bridge Design Specifications is calibrated based on state-specific traffic environments and bridge configurations. As the initial development ... -
Effects of Temperature Variations on the In-Plane Stability of Steel Arch Bridges
(American Society of Civil Engineers, 2012)The in-plane stability of shallow parabolic arches subjected to a central concentrated load and temperature variations was investigated in this paper. The virtual work principle method was used to establish the non-linear ... -
Lessons Learned from the Damaged Huilan Interchange in the 2008 Wenchuan Earthquake
(American Society of Civil Engineers, 2012)A disastrous earthquake struck Wenchuan in China’s Sichuan province in 2008 and caused heavy casualties and structural damage to bridges and buildings. One of the two severely earthquake-damaged curved bridges in China, ... -
Residual Prestress Forces and Shear Capacity of Salvaged Prestressed Concrete Bridge Girders
(American Society of Civil Engineers, 2012)Seven prestressed concrete bridge girders that had been in service for 42 years, and represented two span lengths and reinforcement designs, were tested to determine their effective prestress force and ultimate shear ... -
Field Test and Finite-Element Model of a Skewed Railroad Truss Bridge
(American Society of Civil Engineers, 2012)The skew angle affects the geometry and design of a bridge in many ways. For example, skew angles greater than 20° will affect the bending moment and the shear force in an exterior beam. The U.S. Army Engineer Research and ... -
Case Study of Strategies for Seismic Rehabilitation of Reinforced Concrete Multicolumn Bridge Bents
(American Society of Civil Engineers, 2012)The paper presents a case study for comparing the seismic rehabilitation of four reinforced concrete multicolumn bridge bents typical of older bridges not designed for current seismic code criteria. The types of intervention ... -
Experimental Evaluation of Aluminum Bridge Deck System
(American Society of Civil Engineers, 2012)Most of the movable bridges in the United States have open grid steel decks, primarily because they are factory assembled, lightweight, and easy to install. Open grid steel decks, however, are not as skid resistant as solid ... -
Testing and Analysis of a Deep-Corrugated Large-Span Box Culvert prior to Burial
(American Society of Civil Engineers, 2012)Deep-corrugated steel culverts (corrugation wavelength of 400 mm and amplitude of 150 mm) can be effective alternatives to short-span bridges. Because the corrugation dimensions are of a similar size to their minimum burial ... -
Optimal Resilience- and Cost-Based Postdisaster Intervention Prioritization for Bridges along a Highway Segment
(American Society of Civil Engineers, 2012)In this paper, a general framework for the optimal resilience- and cost-based prioritization of interventions on bridges distributed along a highway connection between two cities that have experienced a disruptive natural ... -
Practical Formula for Cable Tension Estimation by Vibration Method
(American Society of Civil Engineers, 2012)The tension force of cables must be measured accurately during construction and maintenance stages for cable-supported bridge systems. On the basis of the transverse vibration equation of a cable and by using a curve-fitting ... -
Real-Time Dynamic Substructuring Testing of a Bridge Equipped with Friction-Based Seismic Isolators
(American Society of Civil Engineers, 2012)This paper presents a real-time dynamic substructuring (RTDS) test program that was carried out on a bridge structure equipped with seismic isolators with self-centering and friction energy dissipation capabilities. The ... -
Performance Evaluation of Deteriorating Highway Bridges Located in High Seismic Areas
(American Society of Civil Engineers, 2011)This paper studies the life-cycle performance and cost of reinforced concrete highway bridges subjected to earthquake ground motions while they are continuously exposed to the attack of chloride ions. The penetration of ... -
Seismic Behavior of CFT Column and Steel Pile Footings
(American Society of Civil Engineers, 2011)In this study, two column and pile-footing models consisting of concrete-filled steel tube (CFT) columns, reinforced concrete footings, and steel H-piles were designed and constructed at approximately one-fifth scale. The ... -
Energy Damage Detection Strategy Based on Strain Responses for Long-Span Bridge Structures
(American Society of Civil Engineers, 2011)An energy damage detection strategy through disposing strain responses has been developed. First, the strain-based energy dynamic indexes for a system with multiple degrees of freedom were derived from the frequency response ... -
Estimation of Tension in Cables with Intermediate Elastic Supports Using Finite-Element Method
(American Society of Civil Engineers, 2011)Cables with intermediate elastic supports are widely used in bridge engineering, but there is a lack of effective methods for estimating the tensions in these cables. In this paper, an analytical form of the equilibrium ... -
Full-Bridge Deflected Shape Synchronous Measurement in Bridge Loading Test
(American Society of Civil Engineers, 2011)A loading test can provide valuable insight into the behavior and fundamental characteristics of an existing or new bridge. The full-bridge deflected shape in long-span bridges is an important parameter that evaluates the ... -
Shake Table Studies of a Concrete Bridge Pier Utilizing Pipe-Pin Two-Way Hinges
(American Society of Civil Engineers, 2011)Pipe-pin two-way hinge details were recently developed by California Department of Transportation (Caltrans) to eliminate moments while transferring shear and axial loads from integral bridge bent caps to reinforced concrete ... -
Revisit of AASHTO Effective Flange-Width Provisions for Box Girders
(American Society of Civil Engineers, 2011)The nonuniform normal stress distribution along the flange of thin-walled flexural members, such as box girders, is recognized as shear lag effects. Effective flange width is widely used to consider shear lag effects in ... -
