Characteristic Dynamic Increment for Extreme Traffic Loading Events on Short and Medium Span Highway Bridges

O'Brien, Eugene J. ; Cantero, Daniel ; Enright, Bernard ; González, Arturo (Elsevier, 2010-12)

More accurate assessment of safety can prevent unnecessary repair or replacement of existing bridges which in turn can result in great cost savings at network level. The allowance for dynamics is a significant component ...
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 ...
Reduction of bridge dynamic amplification through adjustment of vehicle suspension damping

Harris, Niall K. ; O'Brien, Eugene J. ; González, Arturo (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 ...
