Abstract: The flexural and durability performance of reinforced ultrahigh-performance fiber-reinforced concrete (UHPFRC) beam structures is expected to improve if the steel bars are replaced with carbon fiber–reinforced polymer ...

Abstract: Hybrid double-skin tubular beams (DSTBs) containing an outer fiber-reinforced polymer (FRP) tube, annular concrete, and an inner steel tube have been used as girders or main elements of arch bridges. The fatigue behavior ...

Abstract: The application of recycled aggregate concrete (RAC) has so far mainly been limited to nonstructural components because of its inferior short- and long-term performance compared with normal concrete. Encasement of RAC with ...
