配置不同水平钢筋的自适应分缝剪力墙受剪性能试验研究

EXPERIMENTAL STUDY ON SHEAR BEHAVIOR OF ADAPTIVE-SLIT SHEAR WALLS WITH DIFFERENT HORIZONTAL REINFORCEMENTS

  • 摘要: 进行了3个配置不同水平分布钢筋的自适应分缝剪力墙的拟静力试验,研究了墙体的破坏过程和破坏形态,分析了水平钢筋配筋量对墙体受力性能的影响。结果表明:墙体内部设置型钢可改变墙体的破坏形态,使墙体表现出自适应分缝特性,避免发生脆性破坏;水平钢筋配筋量影响墙体裂缝开展;增加水平钢筋配筋量提高了墙体的受剪承载力、屈服位移角和峰值位移角,但耗能能力有所降低;现行规范中的剪力墙受剪承载力计算公式可用于计算自适应分缝剪力墙。

     

    Abstract: Based on pseudo-static tests of three adaptive slit shear walls with different horizontal reinforcements, the failure process and modes of the shear walls were discussed. Meanwhile, the effects of horizontal steel bars on the performance of adaptive slit shear walls were analyzed. The result shows that the failure mode can be changed by configuring cold-formed steel in the shear walls to avoid brittle fracture, and the shear walls exhibit adaptive slit performance. In the paper, the amount of horizontal steel bars can affect the crack development. The paper also proves that as the horizontal reinforcement increases, the shear capacity, yield displacement angle and peak displacement angle are also improved, but the energy dissipation capacity is reduced. The formulas of shear capacity for shear walls in current codes and standards are suitable for the adaptive slit shear walls.
