Met I. Modelling of the frame buildings interaction with foundations and soil basis

The object of study - stressed - strained state of the system "base-foundation-building" under operational loads and concrete conditions. Purpose of the study - is processes of redistribution of deformations and efforts in the elements of building and soil founding from the action of the operating loading. Purpose - is a decision of scientific and technical task of perfection of method of research interaction work of the system "building-foundation-founding" in concrete engineer-geological terms with the use of dilatancy model of porous environment of the soil foundation and by subsequent prognostication of the stressed - strained state of the system that is prospected. Research methods are: a finite elements method, boundary elements method, finite differences methods, methods of mechanics of soils and building mechanics, methods of mathematical design of experiment. Novelty: the model of interaction work of the building and soil base is improved with the use of method of gradient optimization; set the corresponding relations of redistribution efforts in the central and peripheral areas of the above-ground level part of the system, which is submitted for consideration in the thesis examples 0.6: 1: 2.1, based on the proposed nonlinear mathematical model taking into account the soil dilatancy, improved method of determining the effect of water saturation soil to change the bearing capacity of foundation structures for the numerical method of boundary elements. Industry - construction.
