摘要
为改进型组合钢板剪力墙设计了合理的有限元模型,对纯钢板和3种不同混凝土板厚度以及3种跨高比的组合墙进行了有限元对比模拟分析。结果表明:两侧混凝土板对组合墙的承载力影响不大但可提高其后期刚度,并可有效限制钢板的出平面屈曲;同时,随着跨高比的增大,结构整体承载力有所提高。在此基础上,比较了几组模型的抗剪承载力性能,以及预制墙板对其屈曲荷载的影响,并给予建议的简化模型。可以看出,改进型组合钢板剪力墙有较好的延性以及耗能性能,能充分利用材料的性能。
A reasonable finite element model was designed for improved composite steel plate walls.A steel plate wall and three composite steel plate walls with different concrete wall thickness,and three cross-height ratio composite steel plate walls were performed with finite element analysis.The results showed that:concrete wall on the bearing capacity of composite steel plate walls have little effect but may increase its later stiffness and effectivly limit the steel's buckling outside the plane.Simultaneously,with cross-height ratio increasing,the overall structure capacity has improved.On this basis,compared the effect of the buckling strength and shear strength and proposed a simplified model.The results showed that:improved composite steel plate walls have a good ductility and energy performance to take advantage of the material properties.
