Reinforced concrete shear wall structure capable of automatically resetting
The invention discloses a reinforced concrete shear wall structure capable of automatically resetting. The reinforced concrete shear wall structure comprises a wall body, shear wall confining area longitudinal bars and shear wall non-confining area longitudinal bars, wherein a plurality of shear wall confining area longitudinal bars and a plurality of shear wall non-confining area longitudinal bars are arranged in the wall body, the shear wall confining area longitudinal bars are cut off at the corner, SMA rods are arranged in the cutting position, and the upper and lower longitudinal bars areconnected by the SMA rods by virtue of connecting sleeves. According to the structure, the self characteristic of high-performance materials SMA is used, so that the reinforced concrete shear wall structure is quickly reset, and the post-earthquake recovery time is greatly shortened; additionally, a traditional automatic resetting method of the structure by adopting prestressed bars is avoided, and the construction is convenient.
本发明公开了一种可自复位的钢筋混凝土剪力墙结构，包括墙体、剪力墙约束区纵筋和剪力墙非约束区纵筋。所述墙体的内部设置有若干剪力墙约束区纵筋和若干剪力墙非约束区纵筋，剪力墙约束区纵筋在墙角处截断，截断处设置SMA棒材，SMA棒材通过连接套筒将上下端的纵筋连接。本发明的结构利用高性能材料SMA自身的特性，实现钢筋混凝土剪力墙结构的快速复位，大大减短震后恢复时间；同时避免了传统采用预应力筋来实现结构自复位的做法，施工方便。
