| Abstract: | A piecewise continuous model is taken as the computational model for the overall stability analysis of multi-tower-building structures with enlarged base at the bottom. The stability differential equations for the model are derived. Moreover, the critical loads and the corresponding buckling modes are determined numerically by means of the ODE(Ordinary Differential Equation) Solver, which is a program developed for solving various ODEs, including eigenvalue problems. |
