FRP prestressed system ultra-high-performance concrete T-shaped beam and preparation method thereof
The invention belongs to the related technical field of civil engineering, and discloses an FRP prestressed system ultra-high-performance concrete T-shaped beam and a preparation method thereof. The FRP prestressed system ultra-high-performance concrete T-shaped beam comprises an upper flange, a web plate, a lower flange and an FRP prestress system. The web plate is arranged between the upper flange and the lower flange and used for connecting the upper flange and the lower flange, and an FRP rib/cable is arranged in the center of the upper flange. The FRP rib/cable is used as a prestressed tendon of the T-shaped beam. According to different construction modes, the beam is divided into an integral type beam and a segmental type beam, the segmental type beam comprises the parts, and shear keys are further arranged on the connecting sections of all the segments of the segmental type beam. The ultra-high-performance concrete and the FRP are combined, the excellent mechanical property and durability of the two high-performance materials are fully played, the structural design of the beam is more slender, lighter, thinner and simpler, the problems of a traditional concrete T-shaped beam in the aspects of structural design, durability and construction are solved, the whole life cycle cost of the structure can be saved, and long-term economic benefits are realized.
本发明属于土木工程相关技术领域，并公开了一种FRP预应力体系超高性能混凝土T型梁及其制备方法。该T型梁包括：上翼缘、腹板、下翼缘和FRP预应力体系。其中，腹板设置在上翼缘与下翼缘之间，用于连接上下翼缘，上下翼缘的中心设置FRP筋/索，该FRP筋/索作为T型梁的预应力筋；根据施工方式的不同分为整体式梁和节段式梁，其中节段式梁不仅包括上述部件，在其各节段连接截面还布置剪力键。本发明将超高性能混凝土与FRP相结合，充分发挥两种高性能材料优越的力学性能和耐久性，使梁的结构设计更加纤细、轻薄和简洁，解决传统混凝土T型梁在结构设计、耐久性及施工方面的问题，且能够节约结构全生命周期成本，具有长远的经济效益。
