METHOD FOR CONSTRUCTION AND ANALYSIS OF STRESSED DEFORMED CONDITION OF BUILDINGS, STRUCTURES AND OTHER VERTICALLY EXTENDED OBJECTS ON UNEVENLY COMPRESSED SOILS Russian patent published in 2013 - IPC E02D3/12 

FIELD: construction.

SUBSTANCE: method to to construct buildings, structures and other vertically extended objects on unevenly compressed soils with introduction of additional stiffening elements into a structural scheme of the buildings, structures, such as reinforced concrete belts, impacting soil for changing its properties in process of building erection, measurement of deformations and/or stresses in the main and additional elements of the building, besides, measurements of stresses and deformations are carried out after erection of each group of floors in a surface structure, further, having detected the stressed-deformed condition of the building with account of its stiffness within the floors erected to the moment of measurements, and having assessed acceptability of arisen subsidence and stresses to the moment of measurements, actual deformation and strength characteristics of foundation soils, expected values of stresses and subsidence to the moment of erection of the last building floor, afterwards they decided on necessity and scopes of local impact at the foundation soil until final erection of the building, besides, in case of necessity to impact the foundation soil, they stop erection of the building or continue only in the part, the foundation of which does not require impacting soil, if necessary, the required impact at the soil is carried out, for instance, fixation of cement-sand mortars, afterwards they continue erecting the building, differing by the fact that after erection of another group, for instance, from 2-5 floors of the surface building, they measure the average slope of the upper slab above this group of floors and average slopes of upper slabs above all previously erected groups of floors, further on the basis of the ratio of average slopes of slabs they decide on deformations of the foundation and the stressed-deformed condition of the building to the moment of each measurement, on further development of deformations and change of the stressed-deformed condition to final erection of the building, on the necessity to impact the soil, on termination of building erection or continuation of its construction in the part, the foundation of which does not require impacting soil, on the necessity to introduce additional stiffening elements into the structural scheme, besides, if slope measurements have been made, only upon completion of construction, by the ratio of slab slopes they decide on previously generated deformations of the building, the structure.

EFFECT: higher accuracy and discrimination capacity of analysis of stressed deformed condition of a building, a structure, in process of its erection or upon completion of construction.
