摘要：

The article presents a qualitative and quantitative analysis of the dynamic response of long structures, such as long and high-rise building. A two-dimensional linear model of a building is devised. In this model, the building is represented as a constrained anisotropic plate subjected to base excitation. Consequently, the displacement of the plate is governed by a 2D wave equation with corresponding boundary conditions. The dynamic response of the system, due to base excitation, is being analysed by expanding the displacements in terms of the corresponding eigenfunctions. Also, an analytical expression describing the building motion of translational type is presented. Further analysis is then conducted to determine the response to rotation at the base of the building. The investigation reveals the existence of wave passage effect during the dynamic response of the structure under the optimum conditions on frequencies (low or high) for proper analysis of the resulting deformation of the foundation.
