    摘要:

    双层钢板组合剪力墙结构是一种新型的高层建筑抗侧力构件, 具有良好的应用价值和发展前景,值得研究与推广。根据其他学者的试验成果,结合相关文献中连接件的剪切滑移公式,拟合得出抗剪连接杆的剪力滑移关系,从而建立了双层钢板组合剪力墙的有限元模型。以着重分析组合剪力墙的剪切性质为主要目的,采用相关假定将模型进行简化,并与已有的试验进行对比,验证有限元模型的合理性。运用ANSYS有限元软件对双层钢板组合剪力墙的抗剪性能进行非线性分析,分别考虑抗剪连接杆的间距、钢板的厚度、混凝土板的厚度、混凝土强度等级及组合剪力墙的跨高比等主要影响参数,通过将所得的非线性有限元结果进行比较,结果表明钢板、混凝土板厚度以及混凝土强度对双层钢板组合剪力墙的抗剪性能均有重要的影响,栓钉间距会影响双钢板-混凝土组合剪力墙的受剪破坏模式。

    Abstract:

    Concrete filled double-steel-plate composite wall (CFDSPCW) with shear stud connectors is a new type of lateral-force-resisting construction component for high-rise buildings. In this paper, the in-plane shear resistance of CFDSPCWs is studied with nonlinear finite element analysis using ANSYS. To this end, some assumptions are made to simplify the numerical model. Based on the experimental results and the formula of shear-slip of stud connectors in literature, the constitutive relationship of shear-slip of shear stud connectors is proposed through curve fitting. Then the finite element model of the experimental CFDSPCW is established and validated through experimental results. Thereafter, the study presents the effects of key parameters, including the space of stud connectors, the thicknesses of steel plate and concrete core, the concrete strength and the span-depth ratio of walls, on the shear resistance of CFDSPCWs. The results indicate that the thickness of steel plate and concrete core, and the concrete strength are the most critical factors to affect the shear resistance of CFDSPCWs, and the space of stud connectors affects the failure mode of CFDSPCWs.
