Viscoelastic composite structure based on SMA (Shape Memory Alloy) variable cross-section plate and shear type damper
The invention relates to the technical field of damping and shock absorption, in particular to a viscoelastic composite structure based on an SMA variable cross-section plate and a shear type damper. The viscoelastic composite structure based on the SMA variable cross-section plate comprises a viscoelastic energy dissipation damping component and an SMA self-resetting damping component. The viscoelastic energy dissipation damping component comprises a viscoelastic base body, and the viscoelastic base body can generate shear deformation. The SMA self-resetting damping component is made of a memory alloy material, is of a variable cross-section plate-shaped structure, is embedded in the viscoelastic base body and comprises an energy consumption section located in the middle and connecting sections located at the two ends of the energy consumption section, the connecting sections and the energy consumption section are integrally formed, and the horizontal section size of the energy consumption section is smaller than that of the connecting sections. The shear type damper comprises at least two shear steel plates which are arranged up and down, and at least one viscoelastic composite structure is connected between every two adjacent shear steel plates. The shear type damper is simple in structure and convenient to mount, and has the function of reducing residual deformation of the structure after an earthquake while fully exerting the energy dissipation and shock absorption characteristics of the shear type damper.
本发明涉及属于阻尼减震技术领域，尤其涉及一种基于SMA变截面板的粘弹性复合结构及剪切型阻尼器。基于SMA变截面板的粘弹性复合结构包括粘弹性耗能阻尼构件和SMA自复位阻尼构件；粘弹性耗能阻尼构件包括粘弹性基体，粘弹性基体能发生剪切变形；SMA自复位阻尼构件由记忆合金材料制成，为变截面板状结构，嵌在粘弹性基体内，包括位于中间的耗能段和位于耗能段两端的连接段，连接段与耗能段一体成型，耗能段的水平截面尺寸小于连接段的水平截面尺寸。剪切型阻尼器包括至少两块上下布置的剪切钢板，相邻剪切钢板之间连接有至少一个粘弹性复合结构。本发明构造简单、安装方便，在充分发挥剪切型阻尼器耗能减震特性的同时，兼具减小震后结构残余变形的功能。
