SMA (Shape Memory Alloy)-based self-resetting swing column with replaceable energy dissipation damper
The invention discloses an SMA (Shape Memory Alloy)-based self-resetting swing column with replaceable energy consumption dampers, which relates to the technical field of seismic resistance of constructional engineering, and adopts the technical scheme that the self-resetting swing column comprises a stand column, two energy consumption dampers and a rotatable column foot, the energy dissipation damper comprises a clamping plate, a bottom connecting piece, a top connecting piece, an SMA energy dissipation metal rod, a friction plate and a fastener, the energy dissipation damper is connected with the stand column through the top connecting piece, one end of the clamping plate is connected with the top connecting piece through the fastener, and the other end of the clamping plate is connected with the bottom connecting piece through the fastener; the number of the friction plates is two, rotation constraint of a connecting interface of the main body structure and the foundation slab is relaxed through the energy dissipation dampers and the rotatable column feet, the structure is made to rotate and rub in a limited mode to dissipate earthquake energy, the energy dissipation dampers generate up-down sliding friction to dissipate the earthquake energy, and damage and residual deformation of the main body structure are reduced.
本发明公开了一种基于SMA的可更换耗能阻尼器的自复位摇摆柱，涉及建筑工程抗震技术领域，其技术方案为，包括立柱、耗能阻尼器、可转动柱脚，所述耗能阻尼器设置有两个，所述耗能阻尼器包括夹板、底部连接件、顶部连接件、SMA耗能金属棒、摩擦板、紧固件，所述耗能阻尼器通过顶部连接件与立柱连接，所述夹板一端通过紧固件与顶部连接件连接，所述夹板的另一端通过紧固件与底部连接件连接，所述摩擦板设置有两个，通过耗能阻尼器与可转动柱脚放松主体结构与基础底板连接界面的转动约束，使结构有限转动和摩擦耗散地震能量，耗能阻尼器发生上下滑动摩擦耗散地震能量，降低主体结构的损伤及残余变形。
