The structural behaviour of composite beams with prefabricated reinforced concrete plate in positive moment zone

摘要

In this study, it was investigated that the bearing behaviour of reinforced concrete beams and steel elements in the positive moment zone. The bearing behaviour and the bearing capacities of the reinforced concrete beams with steel elements agglutinated by the epoxy resin. Moreover, certain model researches are done theoretically to determine the distribution of the sliding and the normal strain throughout the coherence surface of the beams which are composed of the reinforced concrete plate and the steel elements agglutinated with the epoxy resin and equation are suggested for these kind of composite due to the results. Test results indicated that the bonding strength between steel and steel is 470% longer than that of concrete to steel.
