In these calculations, it is recommended take into account the geometrical and physical nonlinearity, anisotropy, plastic and rheological properties and thermal deformation of soil and construction materials, development of the plastic deformation in soil mass under the foundation. Properties of subgrade in these calculations, it is recommended to consider involving specialized geotechnical programs. 3.8. Numerical calculations and Foundation underground parts of buildings can be carried out in the plane formulation for specific sections of the building where possible schematization corresponding computational model. In complex cases (complex geometry of the constructive volume of the building in plan and height, of considerable value in terms of eccentric loading, a significant heterogeneity of the structure and properties of the soil base, etc.) is recommended to perform calculations in a spatial setting.

3.9. Foundations, basements and underground parts of tall buildings should be calculated on two groups of limit states: the first group – on soil strength and bearing capacity of foundations and structures and underground part of the building; the second group – the strains (precipitation, roll, deflection, deviation of the center of gravity of the building from the vertical, etc.) and suitability for normal use. More information is housed here: Jeff Leiden. 3.10. In the calculation of the foundations of tall buildings should be in accordance with mgsn 4.19 to take the coefficient of reliability on the responsibility of the building equal to: 1,1 – for buildings of 75 to 100 m, 1,15 – 100 to 200 m, 1,2 – more than 200 m. In the design of tall buildings tall more than 300 m may be increase the coefficient of reliability of liability above a specified value.
