| Abstract: | In this paper, firstly using the commonly used continuum technique for multi-towers with enlarged base in the lower floors, a new piecewise continuous vibrational model is established. Then, the vibrational differential equations for the model have been derived. Secondly, using the ODE (Ordinary Differential Equation) solver, which is a general-purpose program developed for solving various ODE problems including eigen value problem, the natural frequencies and vibrational modes have been obtained, and the dynamical behaviours for different parameters are discussed. |
