Double-column pier straining beam provided with lead viscoelastic damper
The invention discloses a double-column pier straining beam provided with a lead viscoelastic damper, which comprises a straining beam body, the straining beam body is provided with two straining beam sections, and the lead viscoelastic damper is arranged between the two straining beam sections; the two ends of the lead viscoelastic damper are fixedly connected with the straining beam sections arranged at the corresponding ends of the lead viscoelastic damper through fan-shaped connectors respectively. The lead viscoelastic damper is embedded in the straining beam to improve the stress environment of the straining beam under the action of an earthquake so as to improve the earthquake resistance of the straining beam, the columnar lead core is beneficial to improve the strength of the composite elastomer and improve the buffering and damping capacity of the straining beam, and the stabilizing device can reduce shaking of the novel straining beam in the earthquake, and the structural stability is enhanced. Meanwhile, the lead viscoelastic damper has the advantages of being few in used lead viscoelastic damper assembly, convenient to install, simple in structure, low in cost and the like.
本发明公开了一种安装有铅粘弹性阻尼器的双柱桥墩系梁，包括系梁本体，所述系梁本体具有两个系梁段，两个所述系梁段之间安装有铅粘弹性阻尼器；所述铅粘弹性阻尼器的两端分别通过一个扇形连接器同与之对应一端设有的系梁段固定连接。本发明通过在系梁中内嵌铅粘弹性阻尼器改善系梁在地震作用下的受力环境来提升系梁抵抗地震的能力，其中柱状铅芯有助于提高复合弹性体强度，提升系梁缓冲减震的能力，而稳固装置能减少新型系梁在地震中的晃动，增强结构的稳定性。同时本发明所用铅粘弹性阻尼器组件少，安装方便，具有结构简单，成本低廉等优点。
