Fiber reinforced composite material rib and concrete composite beam

The invention discloses a fiber reinforced composite material rib and concrete composite beam which comprises fiber reinforced composite material ribs and concrete wrapping the peripheries of the fiber reinforced composite material ribs. The concrete wrapping the peripheries of the fiber reinforced composite material ribs in a composite beam stress area is an engineering cement-based composite. According to the composite beam, the reinforcing steel bar consumption is lowered, and the structural durability is high.
