Viscous metal combined energy dissipation type replaceable coupling beam
The invention provides a viscous metal combined energy dissipation type replaceable coupling beam which comprises a replaceable energy dissipation section and non-energy dissipation sections connected to the two ends of the replaceable energy dissipation section. The replaceable energy consumption section comprises two viscous dampers, I-shaped steel and two fixed bottom plates; the two viscous dampers are connected with the fixed bottom plate in parallel, and the I-shaped steel is arranged between the two viscous dampers. Along with relative movement of left and right wall columns of the coupled shear wall, the two ends of the replaceable energy dissipation section are subjected to shear deformation, the two ends of the viscous damper are driven to axially move, and energy dissipation is started under wind vibration and small earthquakes; the I-shaped steel dissipates energy together with the viscous damper through yield deformation under medium and large earthquakes, and the aim of staged combined energy dissipation is achieved. The invention has the advantages of improved comfort, simple structure, strong practicability, full-stage efficient energy consumption, strong shock resistance, concentrated damage, convenience for replacement after disaster and the like.
本发明提出一种黏滞金属组合耗能型可更换连梁，包括可更换耗能段，以及连接在可更换耗能段两端的非消能段。可更换耗能段包括两个黏滞阻尼器，工字型钢以及两块固定底板；两个黏滞阻尼器以并联的方式分别与固定底板连接，工字型钢设置在两个黏滞阻尼器中间。随着联肢剪力墙左右墙肢发生相对运动，可更换耗能段两端发生剪切变形，带动黏滞阻尼器两端发生轴向运动，在风振、小震下开始耗散能量，当可更换耗能段两端剪切变形达到一定程度，工字型钢在中大震下通过屈服变形与黏滞阻尼器一同耗散能量，实现分阶段组合耗能目标。本发明具有提高舒适度，构造简单、实用性强，全阶段高效耗能、抗震能力强，集中损伤、便于灾后可更换等优点。
