The superstructure of the prestressed concrete bridge over the Bay of Guanabara, 7884 M long and 26.6 M wide, links the cities of Rio de Janeiro and Niteroi, in Brazil. It was constructed by the segmental cantilever method, the segments of 110 t being glued together with epoxy resin. This is the largest glued bridge which has been constructed anywhere in the world. Account has been taken of the theories and of data concerning the design of transverse glued joints. An experimental study has been carried out of the structural behaviour of glued joints, on a 1/6 scale model of the bridge. It is apparent that the glued joints do not affect the safety of the structure and that collapse occurs in the same fashion as in a monolithic beam. During construction, an attempt was made to determine the various important characteristics of glued joints from the point of view of construction procedures. The behaviour of the glued joints was studied with the aid of a sample of prismatic concrete made up for this purpose. It is obvious that the glue was not affected in any way by damp surfaces. A procedure for drying the contact surfaces is presented, in view of the possibility of rainfall. /TRRL/
