Abstract

Nowadays, rising intensity of traffic is significant effect on entire world, because the endanger risk of adjacent buildings rises. Endanger risk is caused by traffic vibrations spreading through the bedrock, i.e. by traffic seismicity. Historical buildings are specific group of structures, which are especially sensitive on traffic seismicity effects. The aim of this article is experimental dynamic analysis of traffic seismicity effect on Traction substation historical building in Horný Smokovec, district Poprad in Slovakia. This structure is directly exposed to road and rail traffic effects. The experimental measurements of vibration levels were implemented, whose outputs had been vibration acceleration time records on this structure. In all experimental measurements, vibration levels and its transmission through the bedrock were detected, because of train crossing effecting on tower part of object (because the tower part is nearby the railway and it is also the highest place on building) and vehicle crossing. The study of dynamic interaction is implemented within the amplitude analysis. The spectral analysis and frequency transmission is presented in the paper within the frequency analysis. The evaluation of implemented traffic seismicity experimental dynamic analysis effecting on the traction substation object is the end part of analysis.
