METHOD FOR PROVISION OF EVEN DISTRIBUTION OF VERTICAL STRESS IN BEARING WALLS OF MULTISTORY BUILDING WITH SLAB-PILE FOUNDATION Russian patent published in 2010 - IPC E02D35/00 

FIELD: construction.

SUBSTANCE: invention is related to the field of construction, in particular to provision of even distribution of vertical stress in bearing walls of multistory buildings with slab-pile foundations. Method for provision of even distribution of vertical stress in bearing walls of multistory building with slab-pile foundation consists in the fact that calculation of stressed-deformed condition is carried out in the system "foundation-building" with production of data, which is used to act at foundation by means of its stiffness variation. After calculation of stressed-deformed condition of "foundation-building" system is carried out at the stage of design, when distribution diagrams are built for distribution of vertical stress in bearing walls of multistory building in the area of their coupling to foundation. Peaks are detected in vertical stress distribution diagrams and eliminated by reduction of foundation section stiffness, through displacement of each pile axis in the first row of piles from the side of building facades to its centre relative to edge of building transverse walls at the distance specified by given dependence. Piles, which are nearest to line passing through building centre parallel to its facades are installed relative to this line with lower pitch.

EFFECT: provision of even distribution of vertical stress in bearing walls of multistory building with slab-pile foundation at the stage of design and reduction of material intensity.
