Characteristic dynamic traffic load effects in bridges

O'Brien, Eugene J. ; Rattigan, Paraic ; González, Arturo ; Dowling, Jason ; Znidaric, Ales (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 ...
The effect of vehicle velocity on the dynamic amplification of a vehicle crossing a simply supported bridge

Brady, Sean P. ; O'Brien, Eugene J. ; Znidaric, Ales (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 ...
The effect of vehicle velocity on the dynamic amplification of two vehicles crossing a simply supported bridge.

Brady, Sean P. ; O'Brien, Eugene J. (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 ...
