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。
The construction of steel plate shear walls can improve the structural failure mode and improve the energy dissipation capacity and ductility. In order to systematically and comprehensively contrast the influence of different modified forms on the hysteretic behavior of steel plate shear walls, a nonlinear finite element numerical model was established by using the general finite element software ABAQUS. The quasi-static tests at home and abroad were adopted to validate the numerical analysis method to be true To predict the structure of the force behavior. Through the establishment of eight different forms of improved steel plate shear wall model, the bearing capacity, hysteretic properties, degradation characteristics, fracture properties, failure modes and energy consumption capacity were compared and analyzed, and the ductility of different improved forms of steel shear walls , Out of plane deformation, tensile force on the column and other key issues for engineering applications provide a reference. The analysis results show that the structural hysteretic behavior can be effectively improved by changing the structural form of the structure. In the high seismic intensity zone, the seismic shear resistance, ductility, failure mode, building requirements and economic indicators need to be taken into consideration to select suitable steel plate shear wall to improve the structural form ; Low yield point steel plate shear wall because of its special material, bearing high efficiency, energy dissipation ability, ductile advantage prominent, but need to take measures to curb premature buckling and improve the lateral stiffness.
