Prud'ko O. Calculations of plate foundations on the viscoelastic bases under the dynamics and static loading

The object of the research is the process of foundation plate oscillations of composite form on the elastic or viscoelastic soil base. The purpose of the thesic is the development of analytical methods os the research of statics and dynamics of foundation plates of composite form and structure.The research methods are averaging and asymptotic ones for dynamic calculation of plate foundation with walls. The theoretical and practical results are the proposed and the developed calculation methods of plate foundations on the viscoelastic base under the influence of static and dynamics loading, at their base the methodology in solution of foundation construction has been offered, and reflect their physical nature and lead to the analytical expressions; the problem in analytical calculation of stress–deformed state of wall foundation plates on the elastic and the viscoelastic base under the dynamics and static loading has been solveol, the regularity of influence of turned inelasticity of walls has been found, the asymmetry and the width at the dynamic calculation of wall foundation plates havee been found too, the calculation model of dynamic state of wall foundation place has been received, taking into consideration the influence of viscoelastic material of foundation plate, the task of dynamics of foundation plate with periodical slackenings has been solved. The degree of implementation is the results of the thesis researches which are used during the designing and the construction of the works in automobile service, which is situated in Dnipropetrovs’k, Udarnukiv street, 27. The field of usage is the solution of numerous tasks, which appear during the designing and the analysis of the real state of end – use structures.
