Angle brace type viscoelastic shape memory alloy corrugated plate amplification composite damper
The invention discloses an angle brace type viscoelastic shape memory alloy corrugated plate amplification composite damper which is characterized in that an SMA corrugated steel plate is connected with an upper connecting plate and a lower connecting plate through long round hole bolts, and gaps between the corrugated steel plate and the upper connecting plate and the lower connecting plate are filled with viscoelastic materials. The long round hole is formed, the viscous-elastic material and the SMA metal damper are used in a combined mode, and the viscous-elastic material provides energy consumption while SMA does not participate in work during small earthquakes; the SMA participates in work to provide energy consumption during medium and large earthquakes, and particularly, the SMA can still provide self-resetting capacity to control the development of residual deformation of the structure and improve the recoverability (toughness) of the structure during large earthquakes. The viscoelastic SMA corrugated plate is amplified to amplify the displacement of the composite damper in a scissor angle brace mode, and the ratio of the displacement of the viscoelastic SMA corrugated plate amplified composite damper to the displacement between structural layers is changed by changing the mounting angle of the scissor angle brace.
本发明公开了一种隅撑式粘弹形状记忆合金波纹板放大复合阻尼器，使用长圆孔螺栓将SMA波纹钢板与上下连接板连接，在波纹钢板和上下连接钢板空隙处填充粘弹性材料。本发明通过开长圆孔，结合使用粘弹性材料和SMA金属阻尼器，小震时粘弹性材料提供耗能而SMA不参与工作；中、大震时SMA参与工作提供耗能，特别是大震时，SMA尚能提供自复位能力，控制结构残余变形的发展，提高结构的可恢复性(韧性)。通过剪刀隅撑的方式，放大粘弹SMA波纹板放大复合阻尼器的位移，通过改变剪刀隅撑的安装角度，改变粘弹SMA波纹板放大复合阻尼器的位移与结构层间位移之比。
