The Important Parameter Analysis of the Shear Wall-Foudation System on the Dynamic Behavior
【摘要】 应用有限元—无界元耦合法分析了剪力墙—地基体系的自振特性,阐述了剪力墙—地基体系的力学模型的建立,推导了无界元的单元刚度矩阵,编制了相应的计算程序DYFEM。通过若干算例的计算,分析了地基土弹性模量、墙体埋深、墙体与地基接触面宽度以及层土特性对体系自振特性的影响,得出了一些有参考价值的结论
【Abstract】 The dynamic behavior of the shear wall-foundastion system is analyzed by using of the coupling method of the finite-infinite element. The construction of the mechanical model is elaborated, and the element stiffness matrix of infinite element is deduced. Upon the basis of a computer program (DYFEM) is made. The effect of the elastricity modulus of the soil, the bured depth of the shear wall, the contact width of the shear wal and foundation and the behavior of the soil in layers on the dynamic behavior is analyed through calcullation of the wide range of example. A few valuable of views are obtained.
