Generalized Method and Monitoring Technique for Shear-Strain-Based Bridge Weigh-in-Motion
(American Society of Civil Engineers, 2016)Development and testing of a new type of bridge weigh-in-motion system (BWIM) based on the measurement of shear forces near the supports of the bridges is described. The proposed system is applicable to both determinate ... -
Mechanism of Hanger Oscillation at Suspension Bridges: Buffeting-Induced Resonance
(American Society of Civil Engineers, 2016)This article presents the results of an investigation of the wind-induced resonance of hangers on a long-span suspension bridge. The data from field observations, numerical simulations, and wind tunnel experiments presented ... -
Temperature Analysis of a Long-Span Suspension Bridge Based on Field Monitoring and Numerical Simulation
(American Society of Civil Engineers, 2016)Structural temperature is an important form of loading for bridges, particularly for long-span steel structures. In this study, the temperature distribution of the Humber Bridge in the United Kingdom is investigated using ... -
Performance of Two Real-Life California Bridges under Regional Natural Hazards
(American Society of Civil Engineers, 2016)The performance of two real-life California bridges is assessed under a possible regional multihazard condition involving floods and earthquakes. For flood events with varied frequency, expected scour depths at bridge piers ... -
Quasi-Static Cyclic Testing of Elevated RC Pile-Cap Foundation for Bridge Structures
(American Society of Civil Engineers, 2016)In current practices, the elastic design principle for the seismic design of pile foundations is an overly conservative strategy. In this regard, cyclic lateral loading tests were conducted to investigate the seismic failure ... -
Fast Algorithm and Its Application in Construction Monitoring of Parallel Strand Cables
(American Society of Civil Engineers, 2015)A fast algorithm for determining the installation force of parallel strand cables is proposed in this paper. Because cable-stayed bridges are flexible structures, the algorithm must consider the sag effect of cable stays ... -
Nontarget Vision Sensor for Remote Measurement of Bridge Dynamic Response
(American Society of Civil Engineers, 2015)Displacements of railroad bridges under trainloads need to be closely monitored, but conventional displacement sensors have limitations for use in the field. This paper presents a new vision-based sensor system developed ... -
Performance of Nonseismic PTFE Sliding Bearings When Subjected to Seismic Demands1
(American Society of Civil Engineers, 2016)Laminated elastomeric bridge bearings incorporating a flat sliding layer of polytetrafluoroethylene (PTFE) provide service-level thermal displacement capacity to accommodate movements of a bridge superstructure in regions ... -
Low-Damage Precast Columns for Accelerated Bridge Construction in High Seismic Zones
(American Society of Civil Engineers, 2016)Accelerated bridge construction (ABC) is a feature incorporating new technologies, advanced planning, and new detailing to expedite bridge construction. Accelerated bridge construction offers many benefits, the most important ... -
Change Localization of a Steel-Stringer Bridge through Long-Gauge Strain Measurements
(American Society of Civil Engineers, 2016)Development of the long-gauge fiber-optic sensor provides an excellent opportunity for structural-change localization, because it measures averaged strains over a long gauge length. A practical structural-change localization, ... -
Retrofit of Built-Up Steel Columns: Modeling and Fundamental Behavior
(American Society of Civil Engineers, 2016)Cover plates are often added to built-up steel columns as an effective retrofit method for increasing strength. For retrofitted columns, the original member carries all loads, whereas the added cover plates resist only the ... -
Testing and Evaluation of Polyurethane-Based GFRP Sandwich Bridge Deck Panels with Polyurethane Foam Core
(American Society of Civil Engineers, 2016)This paper presents the evaluation of an innovative low-cost small-scale prototype deck panel under monotonic and fatigue bending. This new system introduces a trapezoidal-shaped polyurethane foam core with a thermoset ... -
Failure Characteristics and Ultimate Load-Carrying Capacity of Redundant Composite Steel Girder Bridges: Case Study
(American Society of Civil Engineers, 2015)With the existence of aging highway bridges within the U.S. transportation network, federal and local agencies typically encounter a wide assortment of maintenance issues ranging from cracking, spalls, delaminations, and ... -
Concrete Hinges and Integral Bridge Piers
(American Society of Civil Engineers, 2016)Concrete hinges are a robust structural concept attributed to Eugène Freyssinet and further developed by Fritz Leonhardt and others. Leonhardt and coworkers also developed simple analysis models that are still used today. ... -
Experimental and Numerical Studies on Nondestructive Evaluation of Grout Quality in Tendon Ducts Using Impact-Echo Method
(American Society of Civil Engineers, 2016)The impact-echo method is applied to evaluate the grout quality in tendon ducts of posttensioned structures nondestructively in the present study. As the main evaluation index, the dominant frequency (DFQ) is obtained from ... -
Short-Term Elongation Variation of Posttensioned Tendons
(American Society of Civil Engineers, 2015)When tension is applied to steel tendons, they elongate in proportion to the tensile force, as predicted by Hooke’s law. This elongation is used by the South African standard on concrete structural works and the South ... -
Interaction between Time-Dependent and Second-Order Effects of Externally Posttensioned Members
(American Society of Civil Engineers, 2015)For external tendon members subjected to sustained loads, the time-dependent effects resulting from concrete creep, shrinkage, and tendon relaxation would interact with the second-order effects resulting from the change ... -
Impact Factors of Simply Supported Prestressed Concrete Girder Bridges due to Vehicle Braking
