Fabricated bridge pier node damper
The invention discloses a fabricated bridge pier node damper which comprises anchoring keys located above and below a segment joint and energy consumption keys arranged across the joint, the anchoring keys and the energy consumption keys are connected into a whole in space, the anchoring keys are symmetrically arranged up and down with the segment joint as the center, anchor holes are formed in the anchoring keys, and the energy consumption keys are connected with the anchoring keys. The anchoring keys are fixed to the fabricated pier sections through high-strength bolts, the energy dissipation keys comprise upper energy dissipation rings, lower energy dissipation rings and hysteretic rings, the upper energy dissipation rings and the lower energy dissipation rings are connected with the upper anchoring keys and the lower anchoring keys respectively, the center connecting line of the hysteretic rings coincides with the joints of the sections, and the hysteretic rings are connected with the upper energy dissipation rings and the lower energy dissipation rings in series to form energy dissipation units. The energy consumption units are connected in parallel through the upper energy consumption rings and the lower energy consumption rings to form damping units, and a plurality of damping units are arranged on the side faces of the segments along the joints to form the node damper of the assembly type pier. The mechanism is reliable in connection, stable in mechanical property, simple and rapid in construction and capable of effectively absorbing and dissipating seismic oscillation energy and ensuring the safety of bridge pier sections and the whole.
本发明公开了装配式桥墩节点阻尼器，包括位于节段接缝上下的锚固键和跨接缝布设的耗能键，锚固键与耗能键在空间联系为一整体，锚固键以节段接缝为中心上、下对称布设，在锚固键上开设锚孔，锚固键通过高强螺栓固定在装配式桥墩节段上，耗能键包括上耗能环、下耗能环及滞回环，上耗能环、下耗能环分别与上、下锚固键连接，滞回环中心连线与节段接缝重合，滞回环与上耗能环、下耗能环串连形成一个耗能单元，耗能单元通过上耗能环、下耗能环并联形成一个阻尼单元，沿接缝在节段侧面布设若干个阻尼单元，形成装配式桥墩的节点阻尼器。本发明机构连接可靠、力学性能稳定、施工简单快速，能够有效吸收耗散地震动能量，确保桥墩节段及整体安全。
