The aim of this thesis is to analyze the effect of the explosion on the bridge piers in order to examine the load-bearing capacity of the piers after the impact of the partial and complete destruction of the pier by the explosion. The introduction is based on explosions in general, the history of explosives and an overview of previous research is given. As part of the above, an examle of the experimental effect of the explosion on scale models of the piers of the Šibenik Bridge, which were performed at the military training ground Cerovac, is given. The main part of the paper is devoted to the analysis of three models of pier damage with a different damage cross-section. This anaysis was performed in the sotware Sofistik, using the finite element method (FEM), and includes the verification of stresses in concrete and column reinforcement, as well as column displacements. The check was performed at characteristic points, ie at the bottom, middle and top of the columns, after damage by an explosion under the action of constant vertical and horizontal force, which increases to the value that the numerical model of the column can take before failure.
