Piston type damper and assembly type concrete node damping system
The invention discloses a piston type damper and an assembly type concrete node damping system. The piston type damper comprises a shell and a first plate, the first plate is arranged in the shell, a first chamber and a second chamber which are arranged in the thickness direction of the first plate are defined in the shell, and the first plate can move in the thickness direction of the first plate; negative Poisson's ratio damping parts are arranged in the first chamber and the second chamber, the negative Poisson's ratio damping parts abut against the position between the first plate and the inner wall of the shell, the two sides of the first plate in the thickness direction are connected with first rods, the ends, away from the first plate, of the first rods are provided with first connecting parts, and the first connecting parts are located on the outer side of the shell. The structure is high in energy dissipation capacity and remarkable in damping effect, the earthquake influence on the prefabricated concrete joint is effectively weakened, and the safety performance of the structure is improved.
本发明公开了一种活塞式阻尼器及装配式混凝土节点阻尼系统。所述活塞式阻尼器包括壳体和第一板，第一板设在壳体内，并在壳体内限定出沿第一板的厚度方向布置的第一室和第二室，第一板沿其厚度方向可移动；在第一室和第二室内设有负泊松比阻尼件，负泊松比阻尼件抵接在第一板和壳体的内壁之间，在第一板的厚度方向的两侧均连接有第一杆，第一杆的远离第一板的一端具有第一连接部，第一连接部位于壳体的外侧。本发明结构耗能能力强，阻尼效果显著，有效地削弱预制装配式混凝土节点所受到的地震影响，提高了结构的安全性能。
