Distributed Fibre Optic Sensing to Assess Support Reactions and Behaviour of Composite Steel Bridges
… that involved beam, model bridge, and field load tests. Five steel beams were instrumented with fibre optic sensors and loaded in simply supported and continuous beam configurations. Disturbed regions in DFOS strain measurements were found to extend a distance equal to the depth of the …

Roll and Yaw Stability Evaluation of Class 8 Trucks with Single and Dual Trailers in Low- and High-speed Driving Conditions
… body lean (or high rollover index), besides the truck elements that have most often been studied. Two roundabout geometries, 140-ft single-lane and a 180-ft double-lane, are examined for various truck load conditions and configurations. The vehicle configurations that are considered are a …

Dynamic response evaluation of fiber-reinforced composite bridge decks and bridges
… mode shapes, acceleration values, dynamic load allowance (DLA) factors, and damping ratios.;Controlled truck load tests are also conducted on three FRP bridges namely Katy Truss Bridge, Market Street Bridge, and Laurel Lick Bridge in the state of West Virginia. The dynamic response …

Dynamic response of highway bridges under a moving truck and development of a rational serviceability requirement
… dynamic response of bridges under a moving truck load. The effect of bridge dynamic parameters and vehicle moving conditions are investigated, which includes bridge frequency, damping ratio, span length, girders distance, bracing, support conditions, truck speed, load sequence, axle's …

Feasibility of fiber reinforced composite materials used in highway bridge superstructures
… and structural steel. The <i>AASHTO</i>¹ HS2O-44 truck load is selected as the standard loading condition of all designs. Loads other than dead load and live load are not considered. Configurations of the bridges are different. Appropriate cross-section of girders are selected according to the …

Fatigue response of fabric reinforced polymeric composites
… the behavior of these composites under fatigue loading.;In this study three fabric based glass FRP composites used in bridge components were tested under fatigue loading. A fatigue life prediction model is proposed, with internal strain energy as damage metric, to predict the useful life of FRP …

Live Load Testing of Appalachia, Va Concrete Arch Bridges for Load Rating Recommendation
… Appalachia, Virginia were selected for live load testing by Virginia Department of Transportation (VDOT). Both bridges have supported an increasing amount of extreme coal truck traffic throughout their service life and are essential to the efficient transport of coal in the region. Because of …

Skewed Bridge Behaviors: Experimental, Analytical, And Numerical Analysis
… for skewed thick plates under transverse load and skewed bridges subjected to truck load were developed. The thick plate solution was obtained in a framework of oblique coordinate system. The governing equation in that system was first derived and the solution was obtained using the …

The First Moving Load Simulator for Testing Bridges in Canada and its Application on a Full Scale Precast Box Girder
… describes the development of a unique Moving Load Simulator (MLS) for testing bridge superstructure with a footprint up to 4x17 m, and its first application to test a full scale B900 prestressed concrete box girder. The aim of the experiment was to verify that the MLS can apply cyclic loading …

Flow Characterization and Redesign of Load-Leveling Valves for Improving Transient Dynamics of Heavy Truck Air Suspensions
… to compare the functionality of two types of load-leveling valves that are commonly used for air suspension systems of commercial trucks. The first valve features a simple disk/slot design and is relatively compact for installation. The second type is larger and has a sophisticated, chambered …
