Fabricated self-resetting shear wall with stress separation and self-adaptive cooperative control
The invention provides a stress separation-self-adaption cooperative control assembly type self-resetting shear wall. The stress separation-self-adaption cooperative control assembly type self-resetting shear wall comprises a shear wall body, two post-earthquake self-resetting friction energy dissipation devices, state-adjustable yield energy dissipation devices and stress separation type matrix limiting devices. The two post-earthquake self-resetting friction energy dissipation devices are arranged on the two sides of the bottom of the shear wall body correspondingly, and each post-earthquake self-resetting friction energy dissipation device comprises a friction damping assembly and a shock insulation pre-pressing disc spring assembly. The stress separation type matrix limiting device comprises a steel support fixedly connected with the bottom of the shear wall body, a load-bearing hinged support enabling the steel support to be hinged to a foundation, and two or more shear-resistant hinged supports symmetrically arranged on the two sides of the load-bearing hinged support. The state-adjustable yield energy dissipation device comprises a plurality of low-yield-point steel plates arranged at intervals, and the upper ends and the lower ends of the low-yield-point steel plates are connected with the top of the steel support and the foundation correspondingly. According to the implementation mode, self-adaptive control over four-level performance targets of small earthquakes, medium earthquakes, large earthquakes and huge earthquakes is achieved.
本发明提供了一种受力分离‑自适应协同控制的装配式自复位剪力墙，包括剪力墙主体、两个震后自复位摩擦耗能装置、状态可调屈服耗能装置以及受力分离式矩阵限位装置；两个震后自复位摩擦耗能装置分别设置到剪力墙主体底部的两侧，包括摩擦阻尼组件以及隔震预压碟簧组件；受力分离式矩阵限位装置包括与剪力墙主体底部固定连接的钢支撑、使钢支撑与基础铰接的承重铰支座以及对称地设置到承重铰支座两侧的两个或者多个抗剪铰支座；状态可调屈服耗能装置包括多个间隔设置的低屈服点钢板，低屈服点钢板的上下两端分别连接钢支撑顶部以及基础。该实施方式实现了对小震、中震、大震和巨震“四水准”性能目标的自适应控制。
