Buckling-restrained self-resetting support based on pre-pressed disc springs and damping and energy dissipation method
The invention discloses an anti-buckling self-resetting support based on pre-pressing disc springs and a damping and energy dissipation method. The buckling-restrained self-resetting support comprises a yieldable core material, a fixed end sealing plate, a movable end connecting plate, a cylinder barrel, a pre-pressing disc spring assembly, an installation auxiliary plate, a movable end sleeve and the like. When the structure vibrates under the action of dynamic loads such as earthquakes and wind, the two ends of the anti-buckling self-resetting support installed on the structure move relatively, the cylinder barrel and the movable end sleeve slide relatively, the yieldable core material in the cylinder barrel reciprocates under the lateral constraint of the cylinder barrel, the pre-pressing disc spring assembly slides under the guiding action of the cylinder barrel, and the anti-buckling self-resetting support is installed on the structure. The yieldable core material and the pre-pressing disc spring assembly deform synchronously to jointly play the roles of energy consumption, limiting and resetting. The damping device is controllable in damping parameter, clear in mechanical model, simple in structure, convenient to install and remarkable in damping effect, has certain self-resetting capacity and can be used for earthquake prevention and disaster reduction of bridges, buildings and other structures.
本申请公开了基于预压碟簧的防屈曲自复位支撑及减震耗能方法。其中，防屈曲自复位支撑包括可屈服芯材、固定端封板、活动端连接板、缸筒、预压碟簧组合件、安装辅助板、活动端套筒等。当结构在地震、风等动载作用下发生振动时，安装于结构上的防屈曲自复位支撑两端产生相对运动，缸筒与活动端套筒相对滑动，缸筒内的可屈服芯材在缸筒的侧向约束下往复运动，预压碟簧组合件在缸筒的导向作用下滑动，可屈服芯材与预压碟簧组合件同步变形，共同发挥耗能、限位、复位作用。本申请阻尼参数可控、力学模型明确、结构简单、安装方便、减振效果显著且具有一定的自复位能力，可用于桥梁、建筑等结构防震减灾。
