【摘要】：單排配筋混凝土剪力墻易在基底施工縫處發(fā)生剪切滑移,影響其抗震性能。為了解在剪力墻底部配置斜向鋼筋對大洞口率單排配筋混凝土雙肢墻的抗震性能影響,對1個底部配置斜筋的雙肢墻和1個未配置斜筋的雙肢墻進行了低周反復荷載試驗,并用ABAQUS有限元軟件進行了數(shù)值模擬分析,研究了試驗?zāi)Ｐ偷钠茐奶卣�、滯回性能、承載力、延性、剛度和耗能能力。結(jié)果表明:對于洞口率較大的單排配筋混凝土雙肢墻,在保持墻肢總配筋量不變條件下,墻肢底部適當配置斜向鋼筋可限制其剪切變形發(fā)展,避免墻肢底部施工縫處發(fā)生剪切滑移現(xiàn)象,對雙肢墻的延性和耗能能力有一定的提高作用。
[Abstract]:Single row reinforced concrete shear wall is prone to shear slip at the joint of the base construction. In order to understand the effect of inclined reinforcement at the bottom of shear wall on the seismic behavior of single row reinforced concrete double-legged wall with large hole rate. The low cycle repeated load tests were carried out on a double-leg wall with inclined reinforcement at the bottom and a double-leg wall without a inclined reinforcement, and the numerical simulation was carried out with ABAQUS finite element software. The failure characteristics, hysteretic performance, bearing capacity, ductility, stiffness and energy dissipation capacity of the test model are studied. Under the condition that the total reinforcement quantity of the wall limb is kept constant, the shear deformation development of the wall limb can be restricted by the proper arrangement of oblique reinforcement at the bottom of the wall limb, and the phenomenon of shear slip at the construction joint at the bottom of the wall limb can be avoided. It can improve the ductility and energy dissipation ability of double-limb wall to some extent.
