MODULS OF SUBGRADE REACTION WITH DIFFERENT NORMS

Abstract The paper discusses the model of the interaction of the building and the soil (foundation) under static loads and their joint work determines the stressed-deformed state of the structure. The calculation was carried out using the computer software complex “LIRA SAPR 2024”, which is based on the finite element method. The calculation was carried out with the building stiffness varying (the thickness of the foundation slab varies), and various methods of calculation for a flexible foundation were also used. The results obtained were analyzed. In the examples considered in the paper, various construction numbers and rules (“SP22.13330.2011/2016”, “SP 50-101-2004”, “DBN B.2.1-10:2009”, “SNIP 2.02.01.-83”). The calculation was carried out using the computer software complex “LIRA SAPR 2024”, which is based on the finite element method “FEM”.
