FRP rib high-strength steel-UHPC composite beam
The invention belongs to the technical field of bridge engineering, and particularly relates to an FRP rib high-strength steel-UHPC composite beam. The composite beam is composed of FRP ribs, a high-strength steel beam and a UHPC plate. The high-strength steel beam is composed of a perforated plate, an upper flange, a lower flange and a web. The FRP penetrating ribs penetrate through holes of the perforated plate, the lower layer longitudinal FRP ribs are bound, then the upper layer longitudinal FRP ribs and the upper layer transverse FRP ribs are bound on the perforated plate, and finally UHPC is poured to be combined into a whole. The structure is mainly used for the hogging moment area of the bridge, the compression resistance of the UHPC, the tensile property of the high-strength steel and the excellent tensile property of the FRP rib can be exerted through the structure, and the structure has the advantages of being good in corrosion resistance and ductility and easy and convenient to construct. And the method has a relatively wide application prospect in the field of bridge engineering.
本发明属于桥梁工程技术领域，具体涉及一种FRP筋高强钢‑UHPC组合梁。该组合梁由FRP筋、高强钢梁以及UHPC板组成、高强钢梁由开孔板、上翼缘、下翼缘、腹板四部分组成。在开孔板孔洞内穿过FRP贯通筋，并绑扎下层纵向FRP筋，然后在开孔板上绑扎上层纵、横向FRP筋，最后浇注UHPC组合成一体。本发明主要用于桥梁的负弯矩区，这种结构能够发挥UHPC的抗压性能、高强钢的抗拉性能以及FRP筋优越的抗拉性能，本发明具有抗腐蚀性能好，延性好、施工简便的优点。在桥梁工程领域具有较为广阔的应用前景。
