Abstract
The small and medium span bridges constructed in the 50-60s of the last century with span structures of prefabricated reinforced concrete beams according to the typical project of 1956 year currently do not meet modern exploitative requirements and require reconstruction with bringing of their technical characteristics in accordance to the requirements of the current design norms for new bridges. The design and technical condition of the bridge with span structures built in the 60s of the last century by the TP-56 and the constructive decisions of its reconstruction with the expansion of the span structure by using developed in GNDL-88 of Lviv Polytechnic National University the construction of the collapsible-monolithic superimposed plate with simultaneous strengthening of beams by changing their static scheme from freely adjoining to jamming on supports are described. Static tests of the span structure after the reconstruction confirmed the effectiveness of the adopted design solutions and sufficient load-carrying capacity of the reconstructed bridge to perceive normalized temporary loads A15 and NK-100.
