A 3D numerical prediction model for road traffic induced vibrations, accounting for dynamic soil-structure interaction at the source and the structure, is developed. First, this paper deals with the essential elements of the numerical prediction model. Second, the experimental setup is discussed. Vibration measurements are performed in and near a single(More)
In Krylov's analytical prediction model, the free field vibration response during the passage of a train is written as the superposition of the effect of all sleeper forces, using Lamb's approximate solution for the Green's function of a halfspace. When this formulation is extended with the Green's functions of a layered soil, considerable computational(More)
This paper presents results of experimental and numerical studies concerning the dynamic effects of the Rapid Impact Compactor (RIC) on its environment. The RIC is a dynamic compaction device for middle-deep ground improvement based on the piling hammer technology used to increase the bearing capacity of soils through controlled impacts. The procedure of(More)
— Wind induced ovalling vibrations were observed during a storm in October 2002 on several empty silos of a closely spaced group consisting of 8 by 5 thin-walled silos in the port of Antwerp (Belgium). To clarify the cause and location of the observed silo vibrations, a thorough analysis of the aerodynamic pressures on the silo surfaces is required.(More)
Wind induced ovalling vibrations have been reported to occur on several empty, flexible silo structures in group arrangement. The focus in this paper is on the numerical prediction of this phenomenon by simulating the wind flow around a single silo and taking into account the interaction of the wind flow with the structural response. The importance of the(More)
Wind induced ovalling vibrations were observed during a storm in October 2002 on several empty silos of a closely spaced group consisting of 8 by 5 thin-walled silos in the port of Antwerp (Belgium). In the present study, it is investigated if the observed ovalling oscillations can be numerically predicted. To this end, the silo structures are modeled using(More)

A numerical prediction model for road traffic induced vibrations is developed. Dynamic soil-structure interaction at the source and the structure is accounted for. The first objective is to present the essential elements of the numerical prediction model. Secondly, experimental data will be used for the validation of the numerical model. Therefore,(More)
