英文摘要： Recent years, the development and application of high performance fiber reinforced concrete and high strength steel gained more and more attention in civil engineering. To overcome the difficulty of in-site cast for high performance fiber reinforced concrete and the site-welded difficulty for high strength steel, a novel prefabricated composite beam of high-strength steel and high performance fiber reinforced concrete is proposed. The high strength steel and the high performance fiber reinforced concrete slab is connected through high strength bolted shear connectors. This project focus on the the experimental study on the shear behavior and strength of bolted shear connector, and the flexural behavior and capacity of the prefabricated composite beam. Numerical simulation and theoretical analysis also will be conducted to this research. The results of this research are of significant importance on promoting the development and application of high strength steel and high performance fiber reinforced concrete in composite structural, and providing guidance and suggestion to the their practical application in civil engineering.
