Although the term composite structures can be taken to comprise a large number of structural types, it is usually confined to members which are composed of two (or more) components. Familiar examples are laminated timber frames, steel-concrete beams or slabs, and concrete-concrete beams or slabs. The present report is concerned only with the behavior of beams or slabs comprising two concrete components. This structural type, embodying the combination of precast concrete and in-situ concrete, is increasingly being used in building construction. The specific problems arising in connection with a structure of this kind are bound up with the presence of a contact surface, or interface, between the two components, where forces have to be transmitted from one component to the other. This transmission has to be achieved in some appropriate manner through concrete-to-concrete bond or, in the absence of bond, by means of suitably chosen reinforcement and possible interfacial friction. As there was still some lack of knowledge concerning the manner in which good co-operation between the two components of a composite concrete structure can be ensured, the CUR Committee C 19 'Co-operation of precast beams with in-situ concrete', which has been set up for the purpose, was asked to investigate the problem. The result of that research comprising a study of the literature as well as experimental investigations are contained in the present report.
