Steel bar UHPC-core concrete filled steel tube composite column and design and construction method thereof
The invention relates to a steel bar UHPC-core concrete filled steel tube combination column and a design and construction method thereof. The steel bar UHPC-core concrete filled steel tube combination column comprises a first steel bar UHPC-core concrete combination column body and a second steel bar UHPC-core concrete combination column body located above the first steel bar UHPC-core concrete combination column body. Each of the first steel bar UHPC-core concrete combination column and the second steel bar UHPC-core concrete combination column sequentially comprises core concrete, a steel pipe and a steel bar UHPC from inside to outside, the steel bar UHPC comprises a steel bar cage and an outer layer UHPC poured around the steel bar cage, the core concrete is poured in the steel pipe, and the outer layer UHPC is poured in the steel pipe. The top end of the lower steel pipe is welded to the bottom end of the other steel pipe, and the steel reinforcement cage is arranged on the peripheral sides of the steel pipes in a sleeving mode. The invention relates to the technical field of steel bar UHPC-core concrete filled steel tube composite columns. The steel bar UHPC-core concrete filled steel tube composite column formed by the invention not only can improve the brittleness of UHPC, but also can give full play to the strength of the core concrete filled steel tube, and improves the ductility and anti-seismic property of the whole member.
本发明涉及一种钢筋UHPC‑核心钢管混凝土组合柱及其设计与施工方法，包括第一钢筋UHPC‑核心混凝土组合柱和位于所述第一钢筋UHPC‑核心混凝土组合柱上方的第二钢筋UHPC‑核心混凝土组合柱，所述第一钢筋UHPC‑核心混凝土组合柱和所述第二钢筋UHPC‑核心混凝土组合柱均从内至外依次包括核心混凝土、钢管和钢筋UHPC，钢筋UHPC包括钢筋笼和浇筑在钢筋笼周围的外层UHPC，所述核心混凝土浇筑于所述钢管内，位于下方的钢管顶端与另一个所述钢管底端相焊接，所述钢筋笼套设在钢管外周侧。本发明涉及钢筋UHPC‑核心钢管混凝土组合柱的技术领域。本发明形成的钢筋UHPC‑核心钢管混凝土组合柱既能够改善UHPC的脆性，同时又充分发挥核心钢管混凝土的强度，提升构件整体的延性和抗震性能。
