Axial stepped viscoelastic damper
The invention discloses an axial stepped viscoelastic damper. The axial stepped viscoelastic damper comprises a sleeve and a first-order traction tube, wherein the sleeve and the first-order traction tube are hollow, and one end of each of the sleeve and the first-order traction tube is open; an inner tube is arranged in the sleeve; the first-order traction tube is inserted between the sleeve and the inner tube from the open end of the sleeve; a first-order viscoelastic damping layer is arranged between the first-order traction tube and the inner tube; a stop ring is arranged on the edge of one end, in the sleeve, of the first-order traction tube; a stop piece is arranged at one end, outside the sleeve, of the first-order traction tube; a second-order traction tube is arranged between the sleeve and the first-order traction tube; the second-order traction tube is shorter than the first-order traction tube; a second-order viscoelastic damping layer is arranged between the sleeve and the second-order traction tube; a first connector is arranged at one end, far away from the opening, of the sleeve; and a second connector is arranged outwards on the stop piece. The axial stepped viscoelastic damper disclosed by the invention is different in energy dissipation capacity under the action of different seismic forces, realizes self-adaption of the energy dissipation capacity of the damper to structural response under the action of different seismic forces, realizes axial action energy dissipation, and can be connected with a structure in a supporting manner.
本发明公开了一种轴向分阶粘弹性阻尼器，包括套管及一阶牵拉管，套管及一阶牵拉管均中空一端开口，套管内设置有内管，一阶牵拉管从套管的开口端插入到套管与内管之间，一阶牵拉管与内管之间设置有一阶粘弹性阻尼层；一阶牵拉管于套管内一端的边缘设置有档环，一阶牵拉管于套管外的一端设置有挡片，套管与一阶牵拉管之间设置有二阶牵拉管，二阶牵拉管小于一阶牵拉管的长度，套管与二阶牵拉管之间设置有二阶粘弹性阻尼层；套管远离其开口的一端设置有第一连接头，挡片向外设置有第二连接头。本发明能够在不同地震力作用下耗能能力不同，做到不同的地震作用下阻尼器耗能能力对结构反应的自适应，同时实现轴向作用耗能，可与结构支撑式连接。
