NUMERICAL MODELLING OF THE DYNAMIC IMPACT OF A CARGO VEHICLE ON A BUILDING FOUNDATION
Moving transport is one of the main sources of technogenic vibration impact on nearby buildings and structures. But there is a problem when trying to take into account the impact of vehicles in various calculations. It is lack of rationing of the vibration impact of motor transport in Russia presently. Therefore, the study of the impact of vehicles on the foundations of buildings and structures is relevant. During the research, the goal was to build an adequate numerical model of the dynamic impact of a single vehicle on an existing building using data obtained by express methods of multichannel analysis of surface waves. The results of numerical modelling are compared with the data of field studies to verify the adequacy of the numerical model. In general, the results are close to full-scale values: the arrangement is not more than 14 % for the maximum vertical component of the acceleration and not more than 5 % for the maximum horizontal component for a cargo vehicle and a bus. Additional studies of calculation of the dimensions of wheel contact spot are required to obtain more accurate results of numerical modelling. The developed model is adequate for a single vehicle of large mass.
