[2210] A STUDY ON PERFORMANCE IN FLEXURE OF RC BEAMS STRENGTHENED WITH PRECAST CARBON-FRCM PLATE COMPOSITES
キーワード：fatigue, flexural performance, precast Carbon-FRCM, static, structural strengthening
Fabric reinforced cementitious matrix (FRCM) represents an innovative composite for structural strengthening. This paper presents the flexural performance of Carbon-FRCM strengthened RC beams under static and fatigue loading. The precast Carbon-FRCM plate was adopted instead of cast-in-situ FRCM. Results show that it is effective in strengthening and prolonging fatigue life of RC beams. The layers of carbon fabric mesh in precast Carbon-FRCM plate controlled the failure mode of beams in static loading and fatigue properties of steel bars was the governing factor for fatigue life of beams.
