Usage of the «BRNL-FT» program for foundation calculation using the method of the predefined equated soil settlements

The article considers the use of developed software, which is designed for spread foundation calculation using proposed method of predefined (by project designer) equated settlements. This method allows to decrease differential settlements to minimum acceptable value and to prevent the emergence of settlement cracks in building structures. Problem statement: Modern calculation of soils (according to the Russian building code «SP 22.13330.2011») limits an actual soil pressure Pi by means of design resistance of a soil R. At the same time the pressure range (R<Pi<Pult) is not widely used. This circumstance makes actual development of the spread foundation calculation method using specified pressure range. The purpose of the article is to improve the spread foundation calculation method in respect of reduction of difficulty to apply of proposed method by developing the software. Basics: Proposed method of foundation design is based on the nonlinearity coefficient of elasto-plastic deformation of soil and is used in the developed program «BRNL-FT». This program allows designing new and reconstructed foundations. Conclusion «BRNL-FT» allows designing foundations on the soils, which are at the nonlinear stage of deformation. Consideration of the nonlinear stage makes possible to take more economical design solutions and promotes development of the resource-saving technologies in foundation engineering.
