RISFull-Scale Bridge Finite-Element Model Calibration Using Measured Frequency-Response Functions
Publisher: American Society of Civil Engineers
Prediction of Absorbed, Inert, and Effective Bituminous Quantities in Reclaimed Asphalt Pavement
Publisher: American Society of Civil Engineers
Abstract: This paper presents methods to predict quantities of absorbed, inert, and effective bituminous material in reclaimed asphalt pavement (RAP) for particular sets of conditions; three RAP sources were investigated. The approach ...
Performance Predictions of a Moisture Management Device for Fuel Cell Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Moisture management in proton exchange membrane fuel cells is crucial to durability and performance. This frequently requires external humidification of the reactant gas streams to maintain ...
An Expermentally Validated Model for Two-Phase Pressure Drop in the Intermittent Flow Regime for Noncircular Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the development of an experimentally validated model for pressure drop during intermittent flow of condensing refrigerant R134a in horizontal, noncircular microchannels. Two-phase ...
Measurements of Sediment Erosion and Transport with the Adjustable Shear Stress Erosion and Transport Flume
Publisher: American Society of Civil Engineers
Abstract: Soil and sediments play an important role in water management and water quality. Issues such as water turbidity, associated contaminants, reservoir sedimentation, undesirable erosion and scour, and aquatic habitat are all ...
Combustion Assessment of a 50% Algae-Based HRD76 Fuel and 50% Conventional F76 Military Diesel Fuel Blend
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As part of the United States Navy green energy initiative, engineers at Rolls-Royce and NAVSEA conducted a combustion assessment for a blend of 50% algae-derived HRD76 biofuel and 50% conventional ...
Instrumentation, Nondestructive Testing, and Finite-Element Model Updating for Bridge Evaluation Using Strain Measurements
Publisher: American Society of Civil Engineers
Abstract: A baseline finite element model was developed for bridge management and calibration using nondestructive test data. The model calibration technique was evaluated on the Vernon Avenue Bridge over the Ware River in Barre, ...
Objective Load Rating of a Steel-Girder Bridge Using Structural Modeling and Health Monitoring
Publisher: American Society of Civil Engineers
Abstract: The future of highway infrastructure in the United States is at a critical junction. Nearly one-third of U.S. bridges are nearing the end of their design life, and one in ten bridges is categorized as structurally deficient. ...
Relationship of Field versus Laboratory Compaction to Hot- and Warm-Mixed Asphalt Rutting Performance
Publisher: ASCE
Abstract: Rutting is a major distress for asphalt pavements. This paper examines the relationship of laboratory- and field-compaction methods to rutting performance based on aggregate packing characteristics. Four hot- and warm-mixed ...
Full-Scale Instrumented Testing and Three-Dimensional Modeling of Airfield Matting Systems
Publisher: American Society of Civil Engineers
Abstract: Matting systems are used for temporary applications on soft soils to reduce ground pressure exerted by aircraft, heavy equipment, vehicles, and construction material. They have been used for military airfields, construction ...
