The invention discloses a concrete structure reinforced by round FRP (fiber-reinforced plastic) confined concrete cores, which comprises external concrete and at least one round FRP confined concrete core, each round FRP confined concrete core comprises a round FRP pipe and core concrete, the cross section of the round FRP pipe is round, the external concrete is poured on the external surfaces of the round FRP pipes, the winding direction of the fibers of the round FRP pipe is a circumferential direction or approximately the circumferential direction, the round FRP pipes are filled with the core concrete, and the core concrete is environment-friendly concrete or ordinary concrete. The concrete structure according to the invention utilizes the novel sustainable material to reduce cost, and the concrete structure is enabled to have the characteristics of high bearing capability, high earthquake resistance, light weight and the like. Since the round FRP confined concrete core is structurally simple, decreases the difficulty of construction when precast in a factory, and can bring high technical and economic benefits, the round FRP confined concrete core can be used in engineering structures, such as high-rises and large-span bridges.
