multi-storey building within the framework of a continuous plate model under seismic effects …

The results of numerical solutions of an axisymmetric two-dimensional problem of a rigid
underground pipeline interaction with elastic-viscous-plastic soil are presented. The pipe …

Based on existing data of experimental studies of underground structure-soil interaction, a
condition for boundary interaction between the underground pipeline and soil was …

This paper is devoted to the development of a method for determining longitudinal stresses
in underground pipelines under periodic dynamic load, taking into account the complex …

The article is devoted to the development of mathematical models and new methods for
solving contact problems of multilayer elements of structures with an inhomogeneous base …

The unsteady-state axisymmetric problem of longitudinal interaction of a cylindrical body
with external elastic medium is considered in the paper. The condition of Coulomb friction is …

In this article are considered some problems of oscillations of underground pipelines under
seismic loading. The resulting system of equations is solved by the finite-difference of the …
