Sažetak
The purpose of dynamic testing of the bridge over the river Dobra was to determine dynamic parameters of the structure (dynamic increment of the structure, relative dumping of vibrations and natural frequencies). These dynamic parameters are of the highest significance for the future diagnostic of structure in exploitation, since they are functions of global stiffness of every structure and are as such the best index of real condition of the structure[1]. The bridge ” DOBRA'' is designed as a semi prefabricated frame structure made of pre-stressed reinforced concrete, which is 180, 629 m long and 14, 40 (14, 90) m wide. The roadway is 10, 70 m wide. Piers are rigidly jointed with span structure. Pier foundations, piers and cantilever piers overhangs as well as whole abutments are made in situ. Prefabricated pre-stressed girders are assembled by a launching truss. Horizontal movements of piers is restrained by cantilever overhangs. The wet nodal points make the prefabricated pre-stressed girders monolith after mounting.
