Abstract :Expansion joints of a bridge are not desirable for riding quality and smooth passage of vehicles in addition to difficulties of assuring good maintenance of highways. Therefore, several techniques have been proposed to construct continuous structures. These techniques have shown undesirable tendencies in economical view points since they require complex processes in field. The main purpose of this experimental research is to investigate general behaviors of the continuous precast composite beams under cyclic loads, where unbonded P.C. bars and epoxy resin are used for connecting two precast beams. The behaviors of this type under static loads have been reported in the previous paper, in which continuity at the connection is guaranteed. The results of this research indicate also excellent continuity under cyclic loads without losing any bending rigidity up to practical limit and the technique proposed herein will improve methods in constructing bridges with multiple-spans.
