不同改进形式钢板剪力墙滞回性能研究

STUDY ON HYSTERETIC PERFORMANCES OF THE IMPROVED STEEL PLATE SHEAR WALLS

  • 摘要: 钢板剪力墙的构造形式能够改善结构破坏模式、提高耗能能力及延性。为了系统全面地对比不同改进构造形式对钢板剪力墙滞回性能的影响,利用通用有限元软件ABAQUS建立非线性有限元数值模型,采用国内外已有拟静力试验,验证数值分析手段能够真实地预测结构的受力行为。通过建立8种不同改进形式的钢板剪力墙模型,对承载性能、滞回性能、退化特性、断裂性能、破坏形态以及耗能能力等问题进行对比分析,探讨不同改进形式钢板剪力墙的延性、平面外变形、拉力场对柱子影响等关键问题,为工程应用提供参考依据。分析结果表明:通过改变结构的构造形式,能够有效改善结构的滞回性能;在高烈度区需要综合考虑抗震性能、延性、破坏形态、建筑要求以及经济指标选取合适的钢板剪力墙改进构造形式;低屈服点钢板剪力墙由于其材料的特殊性,承载效率较高,耗能能力强,延性优势突出,但需要通过一定的措施抑制提早屈曲,提高侧向刚度。

     

    Abstract: Constructional details have a great effect on the performance of steel plate shear wall structures and may also alter the failure modes of the structural members and improve their ductility and energy-dissipating capacity. To comprehensively compare the hysteretic behavior of steel plate shear walls with different details, an elaborate non-linear finite element model is established in ABAQUS. Eight steel shear wall models with different constructional details are established and their hysteretic behavior is compared and discussed in depth in terms of load carrying capacity, hysteretic behavior, degraded characteristics, fracture index, failure modes and energy-dissipating capacity. The ductility, out-of-plane deformation and the effect of tension field on column are also analysed, which could provide references for future engineering applications. The results show that variations in structural constructional details can improve the seismic performance of the structural members effectively; the ductility, failure modes, specified building requirements, and economic indicators should be taken into account comprehensively in the selection of appropriate constructional details of steel plate shear walls; for the material particularity, the low yield point steel plate shear wall has higher load efficiency, larger energy dissipation capacity and better ductility. However, some measures are needed to increase the lateral stiffness.
