Shear wall with embedded damaged element and manufacturing method of shear wall
The shear wall comprises a wall body, constraint edge components and the damage elements, the section of the wall body is rectangular, the constraint edge components are fixed to the left end and the right end of the wall body, a plurality of vertical seams are formed in the middle of the structure of the wall body, the damage elements are attached and fixed into the vertical seams, and the damage elements are in a cuboid shape; the compressive strength of the damage element is lower than that of the wall body, and the ultimate tensile strain of the damage element is higher than that of the wall body. The damage element with lower compressive strength and higher limit tension is arranged in the wall body, so that when damage occurs, the damage occurs on the damage element firstly; when the damaged element is damaged greatly and exits, the shear wall is degraded into a slotted shear wall structure, the wall body of the shear wall is divided into a plurality of shear wall sections with high shear span ratio through the vertical seams, and the stress mechanism is changed from a shear stress mechanism to a bending shear stress mechanism, so that the deformability, the toughness and the shock resistance of the shear wall are improved.
本发明公开了一种内嵌损伤元件的剪力墙，包括墙身、约束边缘构件和损伤元件，墙身的截面呈矩形，墙身的左右两端均固定有约束边缘构件，墙身的结构中间开设有数条竖缝，损伤元件贴合固定于竖缝内，损伤元件呈长方体状；损伤元件的抗压强度低于墙身的抗压强度，损伤元件的极限拉应变高于墙身的极限拉应变。本发明通过在墙身内设置抗压强度更低、极限拉应变更高的损伤元件，使在发生损伤时，损伤将先发生在损伤元件上；当损伤元件的损伤较大退出工作后，该剪力墙退化为开缝的剪力墙结构，通过竖缝将剪力墙的墙身分割为若干个较高剪跨比的剪力墙墙段，受力机制由剪切受力机制转变为弯剪受力机制，以增加剪力墙的变形能力、韧性和抗震性。
