Controllable energy dissipation swing self-resetting structural system
The invention discloses a controllable energy dissipation swing self-reset structural system which comprises an upper structure, a foundation and a spring support connected between the upper structure and the foundation. The spring support is a support which only generates vertical displacement and turning, and the spring support is arranged at the joint of a column body of the upper structure and a foundation; the rigidity of the spring support is differently arranged corresponding to the swing track of the upper structure. According to the invention, the traditional constraint form that the structure is fixedly connected to the foundation is changed, so that a bending deformation, shearing deformation or bending-shearing deformation mode of a structural system under the action of earthquake horizontal force is converted into a controllable swinging mode of the whole structure around a certain axis, which is different from a horizontal shearing shock insulation principle of traditional shock insulation; when a strong earthquake occurs, earthquake energy is dissipated through overall swinging of the upper structure and deformation of the bottom spring support, and transmission of the earthquake energy to the upper structure is reduced. And the structural stability is high, the high self-resetting capacity is achieved, damage to the structure under the action of strong shock can be relieved, and structural safety is protected.
本发明公开了一种可控消能摇摆自复位结构体系，包括上部结构、基础和连接于上部结构和基础之间的弹簧支座；弹簧支座为只发生竖向位移和转角的支座，弹簧支座布设于上部结构的柱体和基础连接处；其中，弹簧支座的刚度对应上部结构摇摆轨迹区别设置。本发明改变了结构固接于基础的传统约束形式，使结构体系受地震力水平力作用出现弯曲变形、剪切变形或弯剪变形模式转化为结构整体围绕某一轴心的可控摇摆模式，不同于传统隔震的水平剪切隔震原理，在发生强震时通过上部结构的整体摇摆和底部弹簧支座的变形耗散地震能量，减少地震能量向上部结构的传递。结构稳定性强且具备较强的自复位能力，能够减轻结构在强震作用下的损伤与破坏，保护结构安全。
