钢筋混凝土双连梁受力性能研究

Mechanical behavior study of reinforced concrete dual coupling beams

通过有限元软件ANSYS分别建立带楼板和不带楼板的双连梁联肢剪力墙结构模型,并在结构顶点施加水平荷载,研究两种模型在水平荷载作用下的受力性能。分析带楼板的双连梁的内力、顶点最大位移、破坏形态、结构极限承载力及延性等特性,并与不带楼板的双连梁进行对比研究。研究表明,带楼板的双连梁与不带楼板的双连梁相比,其极限承载力和抗侧刚度有较大提高,但位移延性有一定程度的降低。

The coupled walls of dual coupling beams structural models with and without slabs were established respectively by means of ANSYS software. Horizontal forces were applied on the summit point of the structure to study the mechanical behaviors of two models under the horizontal forces. Mechanical behaviors of two models were compared such as the internal forces, maximum displacement of summit point, failure mode, structural ultimate bearing capacity and the durability property. Results demonstrate that the ultimate bearing capacity and lateral-resistant stiffness of dual coupling beams with slabs are larger than that of the model without slabs, but the displacement durability is relatively lower.
