FRP profile spliced section-UHPC composite beam
The invention discloses an FRP profile spliced section-UHPC composite beam which comprises an FRP spliced component and a UHPC component. The FRP spliced component is located on the lower portion of the composite beam and comprises a T-shaped FRP pultrusion profile, FRP laminated boards, bolts and resin. The T-shaped FRP pultrusion profiles penetrate through the whole beam, webs of the two T-shaped FRP pultrusion profiles are opposite to form an I shape, and the FRP laminated boards are arranged on the two sides of the webs of the FRP I-shaped beam and connected with resin in the thickness direction through bolts to be spliced into the I-shaped beam. The UHPC component is a concrete solid unit and is located on the upper portion of the composite beam. By adopting the spliced I-shaped FRP-UHPC composite beam, the dead weight of the structure is remarkably reduced, the shear strength of the FRP pultrusion profile beam is improved, the problem that the flexural rigidity of a traditional FRP pultrusion profile beam is insufficient due to the production process problem is solved, the mechanical property of the FRP-UHPC composite structure is brought into full play, and the cracking problem of the hogging moment area of the composite beam is effectively avoided.
本发明公开了一种FRP型材拼合截面‑UHPC组合梁，包括FRP拼合构件和UHPC构件。所述的FRP拼合构件位于组合梁下部，包括T形FRP拉挤型材、FRP层压板、螺栓和树脂。所述T形FRP拉挤型材贯穿整根梁，两个T形FRP拉挤型材腹板相对形成工字，FRP层压板设置在FRP工字梁腹板两侧，采用螺栓与树脂在厚度方向进行连接，拼合成工字梁。所述UHPC构件为混凝土实体单元，位于组合梁上部。本发明采用拼合工字形FRP‑UHPC组合梁显著减轻了结构的自重，提高了FRP拉挤型材梁的抗剪强度，解决了传统FRP拉挤型材梁因生产工艺问题导致的抗弯刚度不足的难题，更充分发挥了FRP‑UHPC组合结构的力学性能，有效避免了组合梁负弯矩区的开裂问题。
