Research Progress on Reinforced Concrete Composite Beam in China

Reinforced concrete composite beam plays a very important role in the precast concrete structure, composite beam research is critical. Based on the research results about it in China, on the one hand, from the traditional composite beams to the improved ones, the various kinds of composite beams were concluded; on the other hand, the applications of new building materials in the composite beams had been included, which included fiber reinforced cement-based composites, steel fiber reinforced concrete, reactive powder concrete and crumb rubber concrete. Through to the both related tests and theoretical studies, the progress of the composite beams was summarized. Finally, the further research was prospected.
