(ASTM International, 2003-11)Systems for weighing vehicles while they are in motion are in widespread use in many countries. The accuracy of these weigh-in-motion (WIM) systems is strongly influenced by the road profile and vehicle dynamics. Systems ...

(Institution of Structural Engineers, 2005-08-16)Site-specific assessment of the loading to which existing bridges are subject has considerable potential for saving on rehabilitation and replacement costs of the bridge stock. Monte Carlo simulations, with traffic ...

Characteristic traffic load effects from a mixture of loading events on short to medium span bridges (Elsevier, 2008-09)In recent years highway bridge load assessment has been recognised as an area through which savings can be made by avoiding unnecessary bridge refurbishment and replacement. Load effects in bridges result from single truck ...

(American Society of Civil Engineering (ASCE), 2006-03)Many authors, using both experimental tests and complex numerical models, have examined the effect of vehicle velocity on a highway bridge’s dynamic amplification. Although these tests and models give valuable quantitative ...

(American Society of Civil Engineering (ASCE), 2006-03)The effect of multiple vehicles on a bridge’s dynamic amplification is a complex problem. Previously authors have examined multiple vehicle presence by constructing elaborate finite element models or undertaking field ...

(Elsevier, 2006-11)Bridge Weigh-In-Motion (B-WIM) is a process by which the axle and gross vehicle weights of vehicles travelling at highway speeds can be determined from instrumented bridges. The traditional method of attaching strain ...
-
(Elsevier, 2006-05)The paper considers the influence of the surface profile on the dynamic amplification of a simply supported bridge when subject to a quarter car vehicle model. The effect of the profile irregularities on the bridge dynamic ...
-
(Elsevier, 2006-05)The concept of a road roughness index for bridge dynamics is developed. The International Roughness Index (IRI) is shown to be very poorly correlated with bridge dynamic amplification as it takes no account of the location ...
-
(Elsevier, 2009-07)When formulating an approach to assess bridge traffic loading with allowance for Vehicle-Bridge Interaction (VBI), a trade-off is necessary between the limited accuracy and computational demands of numerical models and the ...
-
(Elsevier, 2007-05)This paper presents a novel approach to the reduction of short-span bridge dynamic responses to heavy vehicle crossing events. The reductions are achieved through adjustment of the vehicle suspension damping coefficient ...
