High-toughness shear wall and construction method thereof
The invention discloses a high-toughness shear wall and a construction method thereof. The high-toughness shear wall comprises a ground beam, and a shear wall body is mounted on the ground beam; the left side and the right side of the bottom of the shear wall are connected with the ground beam through a supporting structure and a plurality of tension energy dissipation structures; and the middle of the shear wall is connected with the ground beam through prestressed tendons and anti-shear steel bars. The high-toughness shear wall has the advantages of being fast in repairing, low in residual displacement and good in self-resetting, the stress mechanism that a traditional common energy dissipation steel bar is pulled and pressed is changed, the energy dissipation steel bar is only pulled, the phenomenon that the energy dissipation steel bar is damaged too early due to pressing buckling is avoided, the requirements for self-resetting and energy dissipation of the shear wall are met, the defects that a traditional self-resetting shear wall is large in displacement and low in energy dissipation capacity are overcome, replacement is rapid after damage, and the toughness of the shear wall is greatly improved.
本发明公开了一种高韧性剪力墙及其建造方法，包括地梁，地梁上安装有剪力墙；所述剪力墙底部的左、右两侧均通过支撑结构和若干受拉耗能结构与地梁相连；剪力墙中部通过预应力筋和抗剪钢棒与地梁相连。本发明具有快修复，低残余位移，自复位好的优点，改变了传统普通耗能钢筋既受拉又受压的受力机制，使得其只受拉，避免了因受压屈曲而过早破坏的现象，兼顾了剪力墙自复位与耗能的要求，避免了传统自复位剪力墙位移大、耗能能力低的缺点，且损伤后更换迅速，大大提高了其韧性能力。
