Abstract: This paper presents the residual behavior of unreinforced concrete beams repaired with carbon fiber-reinforced polymer (CFRP) sheets in shear subjected to elevated temperatures up to 200°C. An experimental program is ...

Abstract: In the present study, the maximum shear strength of simply supported reinforced concrete beams with rectangular cross section was investigated. In beams with heavy shear reinforcement exceeding a certain limit, concrete ...

Abstract: Failure of concrete beam sections underreinforced with fiber-reinforced polymer (FRP) is initiated by FRP rupture before concrete crushing. In such a case, the typical rectangular stress block based on the balanced failure ...

Abstract: Numerical analysis using a finite-element model was performed to simulate and investigate the long-term behavior of two RC beams with similar steel reinforcement, cast from the same batch of concrete. One beam was a plain ...

Abstract: This study investigates the axial compressive behavior of concrete confined with a newly developed lightweight carbon fabric-reinforced cementitious matrix (FRCM) system, incorporating expanded glass (EG) aggregates and ...
