The purpose of the work is to study dynamic processes, to develop mathematical models and techniques for approximate solution of problems for composed construction elements deformation. Research methods have been numerically analytical. An effective mathematical apparatus has been created to solve the problems of deformation of elements of composed constructions and applied calculations of strength in mechanical systems. A mathematical model and calculation technique have been developed that allow preliminary estimation of the strength and stability of layered structures at the stage of creation and debugging when impact loads are impacted on them. An analysis is made of the possibility of using core theories to study transient processes in elements of viscoelastic structures. Based on the use of the refined rod model of a two-layer viscoelastic design, a method has been developed and formulas have been derived for calculating the longitudinal motions of its components and changing the strain energy along the structure caused by the non-stationary end load. Numerical and analytical studies of the stress-strain state of a number of concrete composed construction elements were carried out. The results of the research can be used in engineering practice.
