Numerical Analysis on the Behavior of Carbon Fiber Grid Reinforced Concrete Members

탄소섬유그리드 보강 콘크리트 부재의 거동에 대한 수치해석적 연구

In this paper we present the results of an analytical investigation on the existing concrete structures which are reinforced with carbon fiber grid. The carbon fiber grid and polymer mortar are utilized in the reinforcement of concrete column, beam, and tunnel lining. The physical and mechanical properties of the carbon fiber grid and polymer mortar were obtained experimentally and then used in the analytical investigation. In the analysis concrete structures are modeled with 3-D solid finite elements and the carbon fiber grid is modeled with space frame elements. Through the investigation reinforcing effect of carbon fiber grid on the existing concrete structures is confirmed.
