【摘要】 在符拉索夫开口簿壁杆件理论平面假定的基础上，本文针对核筒，采用三次B样条有限条方法构造连续化模型，并分别计算其动、势能。针对悬挂部分，分别应用杆系有限元和悬吊体系理论，计算其动、势能。然后，由拉格朗日公式，得到悬挂结构体系的动力方程，并用wilson-θ法求解。最后，结合算例得到了具有实际意义的结论。更多还原

【Abstract】 In this paper, the potential and kinetic energy expressions for the suspension structure with story vibration absorption apparatus are derived. For the core tube, the derivation is conducted using the cubic B spline Finite Stripe Method in which the rigid plane assumption in the Vlasov theory is employed. For the suspension parts, the derivation is processed by applying FM method and the suspension system theory, respectively. The dynamic equations of the structure are set up using the Lagrange equation and the Wilson- Method is used to carry out time-history analysis of the dynamic responses of the structure under earthquake actions. A numerical example is provided to illustrate the good vibration-absorbing effect of the structure.更多还原
