Shear wall with recoverable function after earthquake and anti-seismic toughness evaluation method thereof
The invention discloses a post-earthquake function recoverable shear wall and an anti-seismic toughness evaluation method thereof.The shear wall comprises a rigid partition plate, a common wall body and an ultra-high-performance concrete wall body, the lower end of the ultra-high-performance concrete wall body is fixedly connected with a concrete base, and the upper end of the ultra-high-performance concrete wall body is fixedly connected with the common wall body through the rigid partition plate; the ultra-high performance concrete wall body comprises ultra-high performance concrete, outer side high-strength longitudinal bars, inner side common longitudinal bars and horizontal steel bars, the outer side high-strength longitudinal bars and the inner side common longitudinal bars are arranged on the edge portion and the middle of the ultra-high performance concrete respectively, and the outer side high-strength longitudinal bars are wrapped with thin-wall wave-shaped curved surface sleeves. And the upper ends of the outer high-strength longitudinal bars, the thin-wall wave-shaped curved sleeves and the inner common longitudinal bars are fixedly connected with the rigid partition plate, and the lower ends are fixedly connected with the concrete base. According to the self-resetting reinforced concrete shear wall structure, self-resetting of the wall body is achieved, so that other parts of the reinforced concrete shear wall structure are free of damage or low in damage, the post-earthquake repairing difficulty is reduced, and the post-earthquake function restorability is improved.
本发明公开了一种震后功能可恢复剪力墙及其抗震韧性评估方法，剪力墙包括刚性隔板、普通墙体和超高性能混凝土墙体，超高性能混凝土墙体下端与混凝土底座固定连接，上端通过刚性隔板与普通墙体固定连接；超高性能混凝土墙体包括超高性能混凝土、外侧高强纵筋、内侧普通纵筋和水平钢筋，外侧高强纵筋和内侧普通纵筋分别设置在超高性能混凝土的边缘部位和中部，外侧高强纵筋外围包裹薄壁波浪形曲面套管，外侧高强纵筋、薄壁波浪形曲面套管和内侧普通纵筋的上端与刚性隔板固定连接，下端与混凝土底座固定连接。本发明实现了墙体的自复位，使得钢筋混凝土剪力墙结构的其他部件无损伤或低损伤，降低了震后修复难度，提高了震后功能可恢复性。
