مقاوم سازي دالهاي بتني با الياف FRP

Study and Finite element analysis on reinforced concrete slabs considering less than other members of concrete beam and column, so in this paper we have studied Retrofitting of Concrete slabs using FRP. To this end, 9 reinforced concrete slabs using the ABAQUS software were modeled. Each slab with different configurations and thicknesses using FRP sheet strengthened and validation numerical studies using laboratory data available were evaluated. The results show that use of CFRP sheets in the lower level slab increased significant bending strength and reduced displacement of slab center.
