The study of the traffic‐induced response of a simple frame structure is presented. In particular, the effect of the spatial correlation, among the traffic‐induced ground displacements, is discussed by means of a parametric study to achieve the purpose of outlining those configurations yielding the less‐conservative structural response. Ground excitations are estimated by the model of Hunt ( J. Sound Vib. 1991; 1 :41–51; J. Sound Vib. 1991; 1 :53–70) assuming a quarter‐car vehicle model moving on an uneven roadway placed on the top of a homogeneous half‐space. The structure consists of a rigid slab supported by four columns and subjected by traffic‐induced forces suitably condensed in its center of mass. Copyright © 2008 John Wiley & Sons, Ltd.
