(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 ...

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 ...
-
(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, 2011-12)Most of the current research on dynamic amplification factors caused by traffic flow on a bridge has focused on bending moment effects. Although bending stresses often govern the requirements of the bridge section, sufficient ...
-
(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 ...
-
(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 ...
-
(NRC Research Press / Presses scientifiques du CNRC, 2009-01)Critical static bridge loading scenarios are often expressed in terms of the number of vehicles that are present on the bridge at the time of occurrence of maximum lifetime load effect. For example, 1-truck, 2-truck, 3-truck ...
-
(Institution of Civil Engineers/Thomas Telford Publishing, 2009-06)Most current research on dynamic effects due to traffic load on simply supported bridges focuses on the mid-span section of the bridge, since this location corresponds to the worst static bending moment. However, the maximum ...
-
(Professional Engineering Publishing / SAGE Publications Ltd, 2010)This paper presents the equations of motion for a general articulated road vehicle, with variable numbers of wheels for the tractor and trailer. The equations are applicable to vehicle-bridge dynamic interaction problems ...
-
(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 ...
-
(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 ...
-
(British Institute of Non-Destructive Testing, 2009-08)Pavements and bridges are subject to a continuous degradation due to traffic aggressiveness, ageing and environmental factors. A rational transport policy requires the monitoring of this transport infrastructure in order ...
-
(Taylor & Francis, 2011-11-28)This paper presents a new approach to the modelling of congested traffic loading events on long span bridges. Conventional traffic load models are based on weigh-in-motion data of non-congested traffic, or something similar ...
-
The use of predictive likelihood to estimate the distribution of extreme bridge traffic load effect (Elsevier, 2010-03)To assess the safety of an existing bridge, the loads to which it may be subject in its lifetime are required. Statistical analysis is used to extrapolate a sample of load effect values from the simulation period to the ...
-
(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 ...
