Connecting mode of coupled shear wall with displacement enhancing device and self-resetting energy consumption function
The invention discloses a connecting mode of coupled shear walls with a displacement enhancing device and a self-resetting energy dissipation function, and the structure comprises two shear walls and a connecting unit, each connecting unit comprises a left connecting beam and a right connecting beam which are respectively connected with the shear wall through bolts, an end part limiting device for assembling the left connecting beam and the right connecting beam into a whole, a friction material clamped between the end part limiting device and a web plate of the connecting beam, and an elastic resetting component which is concentrically arranged with the left connecting beam and the right connecting beam. The left coupling beam and the right coupling beam comprise sleeves and T-shaped steel, and flanges of the T-shaped steel in the coupling beams are connected with the threaded sleeves pre-buried in the shear wall through bolts. The strip-shaped groove is formed in the T-shaped steel web, the friction plate and the T-shaped steel web are pressed through the pre-tightening bolt, friction sliding of the friction plate and the T-shaped steel web can be caused by the mutual dislocation mechanism of the left connecting beam and the right connecting beam, and therefore the energy dissipation effect is achieved. The elastic reset assemblies are arranged on the two sides of the sleeve in the vertical direction, and the self-reset function is achieved through elastic potential energy stored by the elastic reset assemblies. The elastic reset assembly is formed by connecting disc spring sets and prestressed tendons in series, the ductility of the structure is greatly improved, and elastic potential energy can be stored in stages. Therefore, the energy consumption function and the recoverable function of the coupled shear wall can be achieved, and the anti-seismic requirements of different levels can be met.
本发明公开了一种具备位移增强装置的自复位耗能功能联肢剪力墙连接方式，所述结构包括两片剪力墙和一个连接单元，所述连接单元包括与剪力墙分别通过螺栓连接的左连梁和右连梁、使左右连梁组装成整体的端部限位装置、夹在端部限位装置与连梁腹板间的摩擦材料，与左右连梁同心布置的弹性复位组件。左右连梁包括套筒和T型钢，连梁中T型钢翼缘与预埋在剪力墙中的带螺纹套筒通过螺栓连接。在T型钢腹板上开条形槽，通过预紧螺栓将摩擦板与T型钢腹板压紧，利用左右连梁的相互错动机制，可引起摩擦板与T型钢腹板的摩擦滑动，从而起到耗能作用。在套筒竖直方向的两侧设置弹性复位组件，通过弹性复位组件储存的弹性势能实现自复位功能。弹性复位组件由串联碟簧组与预应力筋再进行串联的形式组成，极大程度提高了结构的延性，又可分阶段储存弹性势能。由此可实现联肢剪力墙的耗能功能和可恢复功能，且能满足不同层次的抗震需求。
