Bridge roughness index as an indicator of bridge dynamic amplification

O'Brien, Eugene J. ; Li, Yingyan ; González, Arturo (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 ...
The development of a dynamic amplification estimator for bridges with good road profiles

Li, Yingyan ; O'Brien, Eugene J. ; González, Arturo (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 ...
