Abstract: Super tall building bundled tube structure, together with its foundation and the subgrade is simplified equivalently and continuously into a three-dimensional model, a combination of stiffened-thin-wall tubes on semi-infinite elastic subgrade. The steady-state response of the model subject to multi-dimensional harmonic deterministic dynamic loadings was analyzed by semi-analytical method. The resonant response was found, i.e., step change will occur when the frequency of the excitation load is much close to the natural frequency of the structural system. The numerical results show that the analytical model and the method are effective and reasonable. A practicable method for the dynamic analysis of the super tall building bundled-tube structures is thus investigated. Some reasonable and significant conclusions are also presented.
