C-shaped steel-friction damper combined energy dissipation structure and method
The invention relates to a C-shaped steel-friction damper combined energy dissipation structure. The C-shaped steel-friction damper combined energy dissipation structure comprises a connecting base, a large C-shaped steel energy dissipation device and a friction device. The connecting base comprises a left connecting base body and a right connecting base body which are symmetrically arranged, and the large C-shaped steel energy dissipation device and the friction device are installed between the left connecting base body and the right connecting base body. The C-shaped steel-friction damper combined energy dissipation structure is arranged at the connecting position of a pier column and a straining beam, when the structure is subjected to an earthquake load, the large C-shaped steel energy dissipation device can absorb transverse load energy dissipation through deformation, and the friction device absorbs longitudinal load energy dissipation through relative friction of the friction device. The double-column pier with the straining beam is mainly used in the field of bridges, the straining beam can be assembled, replaced and repaired, the whole life cycle cost is reduced, the brittle failure mode of shear failure of the straining beam is changed into ductile failure, the anti-seismic performance of the double-column pier is enhanced, and sufficient energy consumption under the earthquake action is achieved.
本发明是一种C形钢‑摩擦阻尼器组合式耗能构造，该C形钢‑摩擦阻尼器组合式耗能构造包括连接底座、大C形钢耗能装置和摩擦装置；连接底座包括对称设置的左连接底座和右连接底座，大C形钢耗能装置和摩擦装置安装于左连接底座和右连接底座之间；该C形钢‑摩擦阻尼器组合式耗能构造布置于墩柱和系梁的连接位置处，遭受地震荷载时，大C形钢耗能装置通过变形能够吸横向载荷耗能，摩擦装置通过自身相对摩擦吸收纵向载荷耗能。本发明主要用于桥梁领域中的带系梁双柱墩，实现了系梁的可装配、可更换、可修复，降低了全寿命周期成本，变系梁的剪切破坏的脆性破坏模式为延性破坏，增强了双柱墩的抗震性能，实现了地震作用下的充分耗能。
