Development and improvement of methods for the analyses of soil-structure interaction based on theoretical and experimental research

Design and construction of buildings in the complex geotechnical conditions for structural and geotechnical engineers is a problem that can be adequately solved carrying out the detailed analysis of soil-structure interaction. There are a few in situ experiments in this field in the world, so there is no sufficient data required for high-quality analysis. Such studies are proposed by this project with the aim to obtain real indicators of behaviour of foundations, as well as soil of different types and characteristics, to be used for efficient numerical modeling. Expected results of the project are: - Development and improvement of software in terms of implementing some of the more complex nonlinear elastoplastic models in GEOPAK software, which is part of the package PAK for static and dynamic FEM analysis of structures, and is related to geotechnical problems; - Development of specialized software package for calculation of structures in interaction with soil, which would be easy to use in construction practice, in accordance with the regulations for reinforced concrete structure, BAB 87, EC2 and SNIP; - update and improvement of domestic regulation in the field of foundation engineering and compliance with international regulations, ie. with Eurocodes which recommend allowing for soil structure interaction in analysis. This would lead to economical dimensioning, and savings in material and scope of construction works.
