Assembly type frame intelligent damping structure
The invention discloses an assembly type frame intelligent damping structure. The intelligent damping structure comprises a prefabricated beam and prefabricated columns, wherein the prefabricated beamand the prefabricated columns are connected through hinge structures, beam column joint intelligent damping devices are installed below the hinge structures, the beam column joint intelligent dampingdevices comprise first embedded bodies and second embedded bodies, one ends of the first embedded bodies are hinged to one ends of the second embedded bodies, two first fan-shaped steel plates are arranged on the inner side of each first embedded body, a second fan-shaped steel plate is arranged on the inner side of each second embedded body, each second fan-shaped steel plate is arranged betweenthe two first fan-shaped steel plates, a first high-strength bolt is arranged on each second fan-shaped steel plate, a piezoelectric ceramic is arranged on one side of each first high-strength bolt,and the piezoelectric ceramics are connected with a controller. According to the intelligent damping structure, the controller adjusts the voltage of the piezoelectric ceramics under the action of different earthquake loads, so that the rotating friction force and the sliding friction force of the core area are adjusted, the purpose that the overall structure is self-adaptive to earthquake response is achieved, and real-time variable-friction shear resistance under the action of medium and small earthquakes is achieved.
一种装配式框架智能减震结构，包括预制梁和预制柱，预制梁与预制柱通过铰接结构连接，铰接结构下方安装有梁柱结点智能减震装置；梁柱结点智能减震装置包括第一预埋体和第二预埋体，第一预埋体的一端与第二预埋体的一端铰接连接，第一预埋体内侧设置有两块第一扇形钢板；第二预埋体内侧设置有第二扇形钢板，第二扇形钢板设置于两张第一扇形钢板之间；第第二扇形钢板上设置第一高强度螺栓；第一高强度螺栓一侧设置有压电陶瓷，压电陶瓷连接有控制器。本发明中控制器调节在不同地震荷载作用下压电陶瓷的所通电压，从而调节核心区域转动摩擦力、滑动摩擦力，达到整体结构对地震响应自适应目的，以实现中小地震作用下实时变摩擦抗剪。
