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 arranged on the outer surface, so that the integrity of the structure is enhanced, the bearing capacity of the column is improved, and the advantage that the longitudinal thrust rigidity of the double-limb thin-wall high pier column is small is more outstanding.
本发明涉及桥梁桥墩技术领域，尤其涉及一种CFRP‑UHPC双肢薄壁高墩柱。其包括薄壁柱，所述薄壁柱包括本体以及包覆于所述本体外表面的CFRP层；所述本体内部空心，所述本体包括UHPC层。本申请中，将UHPC的超高抗压强度、韧性和耐久性应用于双肢薄壁高墩柱，有效提高墩柱的承载能力与延性性能，使墩柱的抗震性能更佳。同时采用空心结构，由于UHPC材料成本高，采用空心结构不仅不会明显降低墩柱的承载能力，还可以有效节省材料降低成本。此外，在外表面设置CFRP，增强了结构的整体性，提高了柱的承载能力，并且使双肢薄壁高墩柱纵向抗推刚度小的优点更加突出。
