The objective of part II of this paper is to couple the validated source model for free-field traffic-induced vibrations, which has been presented in part I of the paper, to a receiver model that incorporates the structure and accounts for dynamic soil-structure interaction. The incident wave field is applied to the structure and the response is calculated using a subdomain formulation for dynamic soil-structure interaction. A finite element method is applied to the structure, while the unbounded soil domain is calculated with a boundary element method using the Green's functions of a homogeneous or a layered half-space. The results of elaborate in situ experiments in and around a single family dwelling during the passage of a truck on joints in a concrete pavement and on a plywood unevenness, are used for the validation of the numerical prediction model. The predicted structural response during the passage of a truck at a speed v = 50km/h is compared with the experimental results. The agreement between the numerical and the experimental results is very good for the passage on the plywood unevenness and satisfactory for the passage on the joints between the concrete plates.
