Abstract
Continuum plate model in the form of a cantilever anisotropic plate developed in the framework of the bimoment theory of plates describing seismic oscillations of buildings is proposed in this paper as a dynamic model of a building. Formulas for the reduced moduli of elasticity, shear and density of the plate model of a building are given. Longitudinal oscillations of a building are studied using the continuum plate and box-like models of the building with Finite Element Model. Numerical results are obtained in the form of graphs, followed by their analysis.

IntroductionThe effect of earthquakes of various intensities and frequency on the seismic resistance of a wooden building was considered in [1]
Studies in the theory of structures showed that in strength calculation, the study of dynamic behavior and assessment of the stress-strain state of various structures, taking into account physical and geometrical nonlinearity, viscoelastic and anisotropic properties of the material, as well as inhomogeneous structural features under the influence of external impacts are important.The effect of earthquakes of various intensities and frequency on the seismic resistance of a wooden building was considered in [1]

Summary
The effect of earthquakes of various intensities and frequency on the seismic resistance of a wooden building was considered in [1]. Evaluation of seismic resistance was made on the basis of experimental and design-theoretical calculations. Based on the obtained experimental data, a design-theoretical assessment of the frame building was performed on simple and complex models under the effect of earthquakes of various intensities and frequency content. Structurally-nonlinear problems with one-way connections are often encountered in calculation of various types of structures and buildings. Problems considering the friction on the contact and under dynamic action of load present certain difficulties. The study in [2] is devoted to the construction of computational models and methods for solving problems with non-ideal one-way connections under dynamic loading
