Abstract: The technical seismicity is perceived as a negative effect on the environment, buildings and constructions. We mean that seismic vibrations are induced by the force impulse, stochastic process, and artificial source. [1]. In Slovak republic, there is the impact of vibrations on building structures rated in Eurocode 8, however, STN 73 0036 is dealing directly with the technical seismicity. Simultaneously, this norm classifies bridges into the group “U”, therefore into the group that is significant in terms of the technical seismicity. Using the FEM simulations and comparison in similar conditions is important for the analysis of these cases, due to short norm rating of this issue.
