UHPC (Ultra High Performance Concrete) steel truss combined structure
The invention discloses a UHPC steel truss combined structure, and belongs to the technical field of civil engineering frameworks, the UHPC steel truss combined structure comprises a UHPC arch rib, a supply groove is integrally formed in the bottom of the UHPC arch rib, connecting rib plates are fixedly mounted on the two sides of an inner cavity of the supply groove, and a side rib assembly is fixedly connected between the connecting rib plates on the two sides. According to the combined structure, the steel web members of the steel truss part and the UHPC arch rib part are effectively connected through the energy absorption assembly, then the combined structure form of joint stress is adopted, on one hand, the material characteristics of steel and UHPC can be effectively combined, and the mechanical property of the structure is greatly improved; compared with a common reinforced concrete beam and a prestressed concrete beam, the prestressed concrete beam has the advantages of being small in self-structure weight, high in bearing capacity, high in spanning capacity, good in ductility, rapid and convenient to construct and the like. The bending rigidity and the lateral rigidity are large, the overall stability and the local stability are good, the corrosion resistance is high, and the economical efficiency is good.
本发明公开了一种UHPC钢桁组合结构，属于土木工程框架技术领域，包括UHPC拱肋，所述UHPC拱肋底部一体设有供槽，且供槽内腔两侧均固定安装有连接肋板，且两侧连接肋板之间固定连接有侧肋组件。本发明中，通过吸能组件将钢桁架部分的钢腹杆与UHPC拱肋部分有效的连接起来，进而共同受力的组合结构形式，一方面能够有效结合钢材和UHPC两者的材料特性，使得结构的力学性能得到大幅度提升，另一方面，对比普通钢筋混凝土梁和预应力混凝土梁，具有自身结构重量较小、承载力高、跨越能力强、延性好和施工快速便捷等优点，对比纯钢梁，不仅用钢量小且抗冲击性能好，而且抗弯刚度和侧向刚度大、整体和局部稳定性好、耐腐蚀能力强和经济性好的特点。
