Prefabricated concrete filled steel tube buckling restrained brace
The invention relates to the technical field of earthquake resistance of building structures, in particular to a prefabricated concrete filled steel tube buckling restrained brace. The prefabricated concrete-filled steel tube buckling restrained brace comprises a core steel plate and a prefabricated concrete-filled steel tube restraining group, the number of the core steel plates is at least two; and the core steel plate is wrapped by the prefabricated concrete filled steel tube constraint group. According to the technical scheme, the core steel plate is wrapped by the prefabricated concrete-filled steel tube constraint set, the core steel plate does not need to be welded, and the influence of welding residual stress and residual deformation on the mechanical property and the fatigue property of the buckling restrained brace is avoided; prefabrication is adopted, so that the production efficiency is greatly improved, and the production cost is reduced; the number of the core steel plates is at least two, and the effect of increasing the bearing capacity can be achieved by increasing the assembling number of the core steel plates.
本发明涉及建筑结构抗震技术领域，尤其是涉及一种预制装配式钢管混凝土屈曲约束支撑。该预制装配式钢管混凝土屈曲约束支撑包括核心钢板和预制钢管混凝土约束组；所述核心钢板的数量有至少两块；所述预制钢管混凝土约束组包裹所述核心钢板。本发明的技术方案通过预制钢管混凝土约束组包裹所述核心钢板，核心钢板无需焊接，避免焊接残余应力与残余变形对屈曲约束支撑力学性能与疲劳性能的影响；采用预制装配化，极大提高生产效率，降低生产成本；核心钢板的数量为至少两块，可以通过增加核心钢板的装配数量能够达到增加承载力的效果。
