Ultra-high-performance concrete-filled steel tube truss structure suitable for large-span truss girder bridge
The invention relates to the technical field of bridge engineering, in particular to an ultra-high-performance concrete-filled steel tube truss structure suitable for a large-span truss girder bridge, which comprises a plurality of truss sections connected end to end, each truss section comprises a rectangular steel tube truss and a filled concrete structure, and the concrete structure is formed by pouring ultra-high-performance concrete. The rectangular steel tube truss comprises chord members and web members, the chord members adopt ultra-high-performance steel tube concrete members, the web members with larger internal force adopt the ultra-high-performance steel tube concrete members, and the web members with smaller internal force adopt hollow steel tubes. The strength of steel and ultra-high performance concrete materials can be brought into full play, the section size of the truss rod piece is reduced, the defects caused by application of thick steel plates are avoided, the upper structure is light, and the span limitation of an existing steel truss bridge is broken through.
本发明涉及桥梁工程技术领域，尤其涉及一种适用于大跨径桁梁桥的超高性能钢管混凝土桁架结构，包括若干个首尾连接的桁架节段，桁架节段包括矩形钢管桁架和填充混凝土结构，混凝土结构由超高性能混凝土浇筑成型，矩形钢管桁架包括弦杆和腹杆，弦杆采用超高性能钢管混凝土杆件，内力较大的腹杆采用超高性能钢管混凝土杆件，内力较小的腹杆采用空钢管。本发明可以充分发挥钢材和超高性能混凝土材料强度，降低桁架杆件截面尺寸，避免厚钢板应用带来的缺陷，实现上部结构轻量化，突破现有钢桁梁桥跨径限制。
