In this baccalaureus graduate thesis the impact of explosive action on reinforced concrete slabs was analyzed on the bridges, which were demolished (completely or partially) and damaged during the Homeland War. The analysis included 70 bridges consisted of six different types of reinforced concrete slab: slab as a type of superstructure, slab above reinforced/prestressed concrete girders set next to each other and spaced apart reinforced/prestressed concrete girders, slab as upper part of reinforced/prestressed concrete box girder, suspension slab decks and reinforced concrete slabs as a superstructure of suspension bridges and reinforced concrete slabs – steel giders composit superstructure. Through analysis of the behaviour of different types of reinforced concrete slabs it was essential to take into account the influence of important features of the bridge: condition and age of the bridge at the time of explosion, precise place of explosive action, number of spans and cross section of superstructure and the influence of explosive activation on the possibility of further exploitation of the bridge. Furthermore, this work includes the practical demolition of six specimens of reinforced concrete slabs with different grade of compression strength and reinforcing additives (steel and synthetic fibers). In order to determine the degree of damage of reinforced concrete slabs caused by explosive action, the slabs were tested by non-destructive methods (Schmidt hammer, ultrasound device and resipod) before and after the demolition, and the measurement results were compared.
