摘要

摘要: 针对现有钢板剪力墙易出现屈曲，滞回曲线存在“捏缩”现象等问题，提出了一种通过短钢管将两块均匀开孔钢板联系起来的新型双钢板剪力墙。为探究该剪力墙的滞回性能并建立恢复力模型，设计缩尺的剪力墙试件并进行拟静力试验，试验结果表明，试件最终呈现为棋盘式局部鼓曲破坏，滞回曲线饱满。采用ABAQUS建立有限元模型，在模型验证准确的基础上进行了参数分析，得到其滞回曲线及面外变形情况等，分析了管肋厚度、墙板厚度、肋间距、管肋边长、高宽比对剪力墙力学性能的影响。结果表明：墙体承载力分别与管肋厚度、墙板厚度、高宽比等参数呈线性关系；管肋厚度与墙板厚度之间的匹配关系，以及肋间距与管肋边长的关系影响着管肋的屈曲约束效果。最后对有限元计算结果进行回归分析，构建管肋开孔双钢板剪力墙的四折线骨架曲线模型，得到刚度退化的计算公式，最终建立恢复力模型。该模型与有限元结果吻合良好，可以为管肋开孔双钢板剪力墙的工程设计提供依据。

Abstract: Regarding the prevalent issues in conventional steel plate shear wall systems， such as their susceptibility to buckling deformation and the conspicuous pinching effect observed in hysteresis curves， a novel double steel plate shear wall connected by short steel tubes between two uniformly perforated steel plates was proposed. To investigate the hysteretic performance of the shear wall and establish a restoring force model， a scaled shear wall specimen was designed and subjected to quasi-static tests. Experimental results revealed that the shear wall ultimately exhibited a chessboard-pattern local buckling failure mode with full hysteresis curves. Finite element models were established using ABAQUS software. After the model's accuracy was successfully validated， parametric analysis was subsequently performed， obtaining hysteresis curves and out-of-plane deformation characteristics. The effects of tubular stiffener thickness， wall plate thickness， spacing between tubular stiffeners， length of tubular stiffeners， and height-to-width ratio on the mechanical properties of the shear wall were investigated. Results demonstrated that the wall bearing capacity showed linear relationships with tubular stiffener thickness， wall plate thickness， and height-to-width ratio. The buckling restraint effectiveness of tubular stiffeners was influenced by the matching relationship between tubular stiffener thickness and wall plate thickness， as well as the correlation between tubular stiffener spacing and tubular stiffener edge length. Finally， regression analysis of the finite element calculation results enabled the establishment of a quadrilinear skeleton curve model for the perforated double steel plate shear walls with tubular stiffeners. Formulas for stiffness degradation were derived， ultimately leading to the development of a restoring force model. This model demonstrated good agreement with the finite element results， providing a theoretical basis for the engineering design of perforated double steel plate shear walls with tubular stiffeners.
