Assessment dynamic ratio for traffic loading on highway bridges

Caprani, Colin C. ; González, Arturo ; Rattigan, Paraic ; O'Brien, Eugene J. (Taylor & Francis, 2011-11-28)

The determination of characteristic bridge load effect is a complex problem. Usually, statistical extrapolation of simulated static load effects is used to derive a lifetime characteristic static load effect. However, ...
Modeling same-direction two-lane traffic for bridge loading

O'Brien, Eugene J. ; Enright, Bernard (Elsevier, 2011-07)

Many highway bridges carry traffic in two same-direction lanes, and modeling the traffic loading on such bridges has been the subject of numerous studies. Different assumptions have been used to model multiple-presence ...
The use of micro-simulation for congested traffic load modelling of medium- and long-span bridges

O'Brien, Eugene J. ; Hayrapetova, Alisa ; Walsh, Cathal (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 ...
