Abstract

Development of communication lines as well as reducing the distance of its location from buildings contributes to the deterioration of human comfort residing in buildings. For that reason it is necessary to determine the size of this nuisance. This paper presents a comparative analysis in order to determine influence of vibrations originating from selected means of transport for people in buildings using ISO 2631-1, British BS 6472-1 and Polish pr PN/B-02171 standards. The analysis focuses mainly on the parameter called dose of vibrations - VDV. In the comparative analysis - as the load acting on the human - vibration acceleration of ceilings caused by crossing subway, truck, tram and train were used. Presented in the paper analysis show, that each types of considered traffic excitations gives similar results for all concerned standards. In case of BS648 standard values of VDV are smaller in vertical direction than for other standards. However, for extortions, in which in the amplitude-frequency characteristics dominate lower natural frequencies, difference between obtained results decreases.
