摘要

对3个预制双向孔模板中高剪力墙进行了拟静力试验研究,得到了剪跨比和水平钢筋配筋量等参数对墙体受剪性能的影响,采用有限元软件ABAQUS对双向孔模板剪力墙进行了数值模拟分析。研究结果表明:随着剪跨比的提高,墙体的变形能力逐渐增强,刚度退化速率减缓,但墙体的受剪承载力有所降低;增加水平钢筋配筋量可提高墙体的受剪承载力,提高其变形能力。采用内聚力模型可用于模拟双向孔模板内的新旧混凝土结合面,建立的数值分析模型与试验结果吻合良好,可为后续研究提供一定的理论参考。
        Through the quasi-static test of high shear walls in three high rise concrete shear walls built with precast two-way hollow slabs, the effects of shear span ratio and horizontal reinforcement on the shear performance of the wall are obtained. The finite element software ABAQUS is used to simulate the two-way hole template shear wall. The results show that with the increase of the shear-to-span ratio, the deformation resistance of the wall is gradually enhanced, the rate of stiffness degradation is slowed down, but the shear capacity of the wall is reduced. Increasing the amount of reinforcement of the horizontal steel can increase the shear capacity, and improve its resistance to deformation. The cohesion model can be used to simulate the new and old concrete joints in the two-way hole template. The established numerical analysis model agrees well with the experimental results, which can provide a theoretical reference for subsequent research.
