Concrete beam-column joint box type connecting structure with self-resetting SMA energy dissipater
The invention discloses a concrete beam-column joint box type connecting structure with a self-resetting SMA energy dissipater. According to the concrete beam-column joint box type connecting structure, a prefabricated reinforced concrete lower column and a prefabricated reinforced concrete upper column are fixedly connected through a column end connecting piece; the prefabricated reinforced concrete beam and the prefabricated reinforced concrete lower column are fixedly connected through a steel box; and a plurality of self-resetting SMA energy dissipaters comprising self-resetting devices and energy dissipation devices and energy dissipation connecting keys are further symmetrically arranged at the joint of the prefabricated reinforced concrete beam and the prefabricated reinforced concrete lower column. According to the concrete beam-column joint box type connecting structure with the self-resetting SMA energy dissipater, the requirements in the actual design and construction of a fabricated building are met, the assembled beam-column joint is high in bearing capacity and clear and reasonable in damage mode, plastic hinges can be effectively prevented from appearing at the column end, the stable energy dissipation effect can be continuously achieved under the earthquake action, and the energy dissipation efficiency is improved. And the structure can realize self-resetting after an earthquake.
本发明公开了一种带自复位SMA耗能器的混凝土梁柱节点盒式连接结构,包括:预制钢筋混凝土下柱和预制钢筋混凝土上柱通过柱端连接件固定连接;预制钢筋混凝土梁和预制钢筋混凝土下柱通过钢盒固定连接;预制钢筋混凝土梁和预制钢筋混凝土下柱的连接处还对称设有包括自复位装置和耗能装置的若干自复位SMA耗能器以及耗能连接键。本发明提供的带自复位SMA耗能器的混凝土梁柱节点盒式连接结构满足了装配式建筑实际设计与施工中的需要,装配后的梁柱节点承载力高,损伤模式明确、合理,能够有效地避免塑性铰在柱端出现,地震作用下,能够持续发挥稳定耗能效果,震后结构能够实现自复位。
