Abstract: Concrete beams reinforced with a combination of steel and glass fiber-reinforced polymer (GFRP) bars exhibit promising strength, serviceability, and durability. The fatigue performance of concrete beams with hybrid ...

Abstract: Novel fiber-reinforced polymer (FRP) bar-reinforced ultrahigh-performance engineered cementitious composites (UHPECCs) have been proposed recently. This innovative composite structure aims to address two critical challenges: ...

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: Usually, rail materials are exactly affected by the erosion of windblown sand in the desert environment. For this reason, the influence of impact angle, particle velocity, and particle size on the erosion wear behavior of ...

Abstract: Hybrid fiber-reinforced polymer (FRP)–concrete–steel hybrid double-skin tubular columns (DSTCs) consist of an outer FRP tube, an inner steel tube, and a layer of concrete filled between the two tubes. Previous studies have ...

Abstract: Congo red (CR), a harmful pollutant, is increasingly contaminating aquatic environments. The removal of CR from wastewater is important. This study developed a novel graphene–biochar composite (GR-BC) to enhance CR treatment. ...
