Novel external steel bar energy dissipater
The invention discloses an external steel bar energy dissipater which comprises a fan-shaped supporting upper plate, a fan-shaped supporting lower plate and hourglass-shaped steel bar energy dissipation elements. When an earthquake comes, a displacement difference exists between the bridge pier and the bridge pier bearing platform, so that the fan-shaped supporting upper plate shears the hourglass type energy dissipation element, a part of earthquake energy can be absorbed, and damage to the bridge pier caused by the earthquake is avoided. When the hourglass-shaped steel bar energy dissipation element is damaged under the action of an earthquake, the external steel bar energy dissipater can work again by replacing the hourglass-shaped steel bar energy dissipation element.
本发明公开了一种外置钢棒耗能器,包括扇形支撑上板、扇形支撑下板及沙漏状钢棒耗能元件。可安装于自复位桥墩与桥墩承台连接处，地震来临时，桥墩和桥墩承台存在位移差值，使得扇形支撑上板剪切沙漏型耗能元件，从而能够吸收一部分地震能量，避免地震给桥墩带来的损害。沙漏状钢棒耗能元件在地震作用下损坏时，可通过更换，使外置钢棒耗能器重新工作。
