Displacement amplification type viscous damping outrigger truss and design method thereof
The invention relates to the field of damping of building structures, aims to solve the problem of how to reduce the anti-seismic cost of the building structures, and provides a displacement amplification type viscous damping outrigger truss and a design method. The displacement amplification type viscous damping outrigger truss comprises an outrigger truss piece and a viscous damping piece. The outrigger truss piece is connected with the core tube. According to the displacement amplification type viscous damping outrigger truss, the form that the outrigger truss part is hinged to the viscous damping part is adopted, the viscous damping part has a good amplification effect on displacement and speed, the outrigger truss part can also amplify the displacement of the core tube, the double amplification effect enables the viscous damping part to exert the obvious energy dissipation capacity under the earthquake effect, and the energy dissipation capacity of the core tube is greatly improved. Meanwhile, due to the fact that the displacement between the structural layers is amplified, the working efficiency of the viscous damping piece is improved, and the deformation difference between the core tube and the outer frame is reduced, the arrangement number of BRBs can be reduced, the overall rigidity of the structure is reduced, and then the damping design cost of the overall structure is reduced.
本申请涉及建筑结构减震领域，旨在解决如何降低建筑结构的抗震成本的问题，提供位移放大型黏滞阻尼伸臂桁架及设计方法。位移放大型黏滞阻尼伸臂桁架包括伸臂桁架件和黏滞阻尼件。伸臂桁架件连接核心筒。本申请中的位移放大型黏滞阻尼伸臂桁架，采用伸臂桁架件与黏滞阻尼件铰接的形式，黏滞阻尼件对位移和速度具有良好放大效果，伸臂桁架件也能够将核心筒的位移放大，双重放大作用使黏滞阻尼件在地震作用下发挥明显的耗能能力，从而减小核心筒和外部框架的变形，同时，由于结构层间位移被放大，黏滞阻尼件的工作效率得到了提高，核心筒和外部框架的变形差别被缩小，因此可以减少BRB的布置数量，降低结构整体刚度，进而降低整体结构的减震设计成本。
