Damping and energy-consuming type outrigger truss high-rise structure system
The invention relates to the technical field of structural seismic resistance and energy dissipation and seismic mitigation, and particularly relates to a damping and energy-consuming type outrigger truss high-rise structure system. The damping and energy-consuming type outrigger truss high-rise structure system comprises a core tube arranged in the middle of a building, a frame column arranged on the periphery of the building and an outrigger truss arranged between the core tube and the frame column; the outrigger truss comprises an upper chord rod connected with the core tube and the frame column, a lower chord rod arranged below the upper chord rod in parallel and connected with the core tube and the frame column, and a diagonal web rod arranged between the upper chord rod and the lower chord rod; and a damper is vertically arranged on the frame column, one end of the diagonal web rod is connected to the damper, and the other end of the diagonal web rod is connected to the core tube. The reinforcing effect of reducing structure sidesway of a common outrigger truss can be achieved, the overturning moment of the core tube is reduced, and the situation that due to the fact that the outrigger truss is arranged, a relatively weak layer is formed, and consequently floor rigidity and bearing capacity are suddenly changed can be avoided.
本发明涉及结构抗震与消能减震技术领域，尤其是涉及一种减震耗能型伸臂桁架高层结构体系，包括：设置于建筑中间的核心筒；设置于建筑外围的框架柱；设置在核心筒和框架柱之间的伸臂桁架；所述伸臂桁架包括：连接核心筒与框架柱的上弦杆；平行设置于上弦杆下方且连接核心筒与框架柱的下弦杆；以及设置于上弦杆和下弦杆之间的斜腹杆；所述框架柱竖向布置有阻尼器，所述斜腹杆的一端连接于阻尼器，所述斜腹杆的另一端连接于核心筒。本发明既能起到普通伸臂桁架减少结构侧移的加强作用，减小核心筒倾覆弯矩，又能避免因设置伸臂桁架形成相对薄弱层，而产生楼层刚度和承载力突变。
