Self-resetting shear wall with energy consumption amplification function
The invention provides a self-resetting shear wall with an energy consumption amplification function. The self-resetting shear wall comprises a rotating internal friction device located between the bottom of the shear wall and a constraint foundation beam and efficient energy consumption devices symmetrically arranged on the left side and the right side of the rotating internal friction device. Starting from the elastic transformation of the plastic hinge area of the shear wall, the design objective is to realize larger elastic lateral displacement, and the wall foot easy to damage is replaced by an efficient energy consumption device with self-resetting capability through a displacement amplifying device; and meanwhile, the rotating internal friction device is connected with the constraint foundation beam in a self-resetting hinged mode with a variable friction energy dissipation mechanism. The shear wall has a stronger elastic function and can meet the requirement for larger lateral displacement, the wall body is not prone to damage, and wall body resetting is achieved.
本发明提供一种具有耗能放大功能的自复位剪力墙，包括位于剪力墙底部和约束基础梁之间的转动内摩擦装置和对称布置于所述转动内摩擦装置左右两侧的高效耗能装置；本发明从剪力墙塑性铰区的弹性改造出发，以能实现较大弹性侧移为设计目标，将易于受损的墙脚通过位移放大装置替换为具有自复位能力的高效耗能装置，同时转动内摩擦装置与约束基础梁之间的连接关系采用具有变摩擦耗能机制的自复位铰接连接。该剪力墙具有更强的弹性功能，能够满足更大的侧向位移需求，墙体不易发生破坏，并实现墙体复位。
