The effect of the profile irregularities on the bridge dynamic amplification is characterized with a ‘response surface’ giving dynamic amplification due to a ‘unit ramp’ at any location. Even though the dynamic interaction problem is non-linear, the effects of all ramps which together make up a road profile can be calculated separately and added using the ‘response surface’. This superposition process achieves reasonable accuracy for ‘good’ (moderately smooth) surface profiles. An accurate estimate of dynamic amplification for bridges is demonstrated with a wide range of good profiles.||Funding Details:||Not applicable||Type of material:||Journal Article||Publisher:||Elsevier||Copyright (published version):||2005 Elsevier Ltd||Keywords:||Dynamics; Roughness; Bridge; Vehicle||Subject LCSH:||Structural dynamics
