To account for the influence of the pile–soil–structure interaction, a Received in revised form wavenumber domain boundary element method (WDBEM) model for the periodic pile row supporting 8 May 2013 the viaduct is developed using the sequence Fourier transform as well as the boundary element method Accepted 25 September 2013 Available online 23 October 2013 for the elastic medium. By using the WDBEM model for the pile row, the transfer matrices for the beams and piers, the joint conditions at the beam–beam–pier (BBP) junction as well as the periodicity condition Keywords: for the viaduct, the wavenumber domain response of the periodic viaduct to spatially harmonic waves is Periodic viaduct determined. Based on the wavenumber domain response of the viaduct, the space-domain response of Pile–soi
