Non-prestress self-resetting energy dissipation supporting device provided with variable friction damper
The invention discloses a non-prestress self-resetting energy dissipation supporting device provided with a variable friction damper. The non-prestress self-resetting energy dissipation supporting device comprises the variable friction damper, an inner sleeve pipe, a plurality of pre-pull rods arranged in the inner sleeve pipe and an outer sleeve pipe arranged outside the inner sleeve pipe, wherein the variable friction damper comprises an upper friction plate, a middle friction plate and a lower friction plate which are sequentially connected, the contact surface of the upper friction plate and the middle friction plate is an embedded zigzag undulating slope surface, the middle friction plate is connected with the inner sleeve pipe, and the lower friction plate is connected with the outersleeve pipe. The energy dissipation device can dissipate energy under the earthquake action, reduce the interlayer displacement angle and acceleration of a building structure, eliminate or reduce residual deformation and damage of a reinforced concrete frame structure under the earthquake action, effectively avoid obvious plastic deformation of a main body structural member, and meanwhile, due tothe fact that the energy dissipation device is convenient to disassemble and assemble, friction energy consumption devices playing a role in dissipating energy are all in an elastic stage, and the repair cost and difficulty of the structure after an earthquake can be obviously reduced.
本发明公开了一种设有变摩擦阻尼器的无预应力自复位耗能支撑装置，包括变摩擦阻尼器，内套管，设于该内套管里的若干预拉杆以及设于该内套管外的外套管；其中，所述变摩擦阻尼器包括依次相连的上摩擦板、中摩擦板及下摩擦板，上摩擦板和中摩擦板两者的接触面为嵌合的锯齿状起伏坡面，中摩擦板与内管套连接设置，下摩擦板与外管套连接设置。该耗能装置能够消耗地震作用下的能量，减小建筑结构的层间位移角及加速度，消除或降低钢筋混凝土框架结构在地震作用下的残余变形和损坏，有效避免主体结构构件出现明显塑性变形，同时由于其方便拆卸及安装，起到耗散能量的摩擦耗能器均处于弹性阶段，能够明显降低结构震后的修复费用和难度。
