By using the commonly used continuum technique,a new piecewise continuous series - parallel connection model is taken as the computational model for the multi- tower structure linked by spatial corridors and with enlarged base at the bottom. Then, the differential equations of equilibrium for the model are derived. Moreover, the displacements and internal forces of the structure are determined numerically by means of the ODE (Ordinary Differential Equation) solver, which is a program developed for solving various ODEs.
