Connecting structure of cross-layer outrigger truss and viscous damper combined component
The invention belongs to the technical field of energy dissipation and shock absorption of constructional engineering, and discloses a connecting structure of a cross-layer outrigger truss and a viscous damper combined component. According to the technical scheme, the outrigger truss is arranged between a frame column and a core tube, and the outrigger truss is overhung out of the core tube; the outer contour of the vertical face of the outrigger truss is in a big-end-up trapezoid shape; the outrigger truss is arranged in a cross-layer mode; the outrigger truss is located below an upper-layerfloor; a hole is formed in the position, where a diagonal web member and a vertical web member of the outrigger truss penetrate, of a lower-layer floor, so that the outrigger truss penetrates throughthe lower-layer floor; a viscous damper is vertically arranged, and the upper portion of the viscous damper is connected with the upper end of the outrigger truss through a first pin shaft; and the lower portion of the viscous damper is connected with the frame column through a bracket, and the viscous damper is connected with the bracket through a second pin shaft. The problem that in the prior art, the structural rigidity of an outrigger truss is suddenly changed is solved, and meanwhile the energy dissipation and shock absorption effects of the viscous damper are improved.
本发明属于建筑工程消能减震技术领域的一种跨层伸臂桁架与粘滞阻尼器组合构件的连接构造。技术方案为：伸臂桁架置于框架柱和核心筒之间，伸臂桁架从核心筒悬挑出；伸臂桁架的立面外轮廓形状为上大下小的梯形；伸臂桁架跨层布置；伸臂桁架位于上层楼板的下方；下层楼板在伸臂桁架的斜腹杆和竖腹杆穿过的位置开洞，使伸臂桁架穿过下层楼板；粘滞阻尼器竖向放置，粘滞阻尼器的上部与伸臂桁架的上端部采用第一销轴连接；粘滞阻尼器的下部通过牛腿与框架柱连接，粘滞阻尼器与牛腿之间采用第二销轴连接。克服了现有技术中伸臂桁架造成结构刚度突变的问题，同时提升了粘滞阻尼器消能减震的效果。
