CFRP-UHPC double-limb thin-wall high pier stud

The invention relates to the technical field of bridge piers, in particular to a CFRP-UHPC double-limb thin-wall high pier stud. The CFRP-UHPC double-limb thin-wall high pier stud comprises a thin-walled column body, and the thin-walled column body comprises a body and a CFRP layer wrapping the outer surface of the body. The interior of the body is hollow, and the body comprises a UHPC layer. In the CFRP-UHPC double-limb thin-wall high pier stud, the ultrahigh compressive strength, toughness and durability of the UHPC are applied to the double-limb thin-wall high pier stud, so that the bearing capacity and ductility of the pier stud are effectively improved, and the anti-seismic property of the pier stud is better. Meanwhile, the hollow structure is adopted, due to the fact that the UHPC material cost is high, the bearing capacity of the pier column cannot be obviously reduced through the hollow structure, materials can be effectively saved, and the cost can be effectively reduced. Besides, the CFRP is arrang
