000021791 520__ $$2eng$$aTwo cases are examined: The first one examines the possibility of attaining a monolithic connection between deck and piers, in order to avoid using elastomeric bearings and obtain a continuous frame ductile system. The second one examines an innovative prefabrication proposal which, instead of using conventional simply supported precast prestressed beams, uses bilateral precast prestressed cantilevers, leaving gaps of order of 10m at the spans between the cantilevers, which are filled with cast in situ concrete by using suspended formwork in a next construction phase. In this second case the wall-type abutments are connected monolithically with the ends of the deck and are utilized as seismic stoppers. The experimental survey included five test specimens, through which the performance of the monolithic connections of the deck to the piers at the support positions is examined. The two proposals were applied as alternative solutions for the superstructure of real bridges. The first one was applied on a bridge of the PATHE motorway which has 5 spans and a total length of 177.5m, while the second one was applied as alternative solution on a bridge of a motorway in Crete with a length of 400m, which was designed according to the cantilever construction method.
