Abstract
Structural schemes and the construction features of foundation reinforced concrete slabs with effective inserts that designed for building different structures design, including during reconstruction are given. The general configuration and foundation slab design for further construction in Ternopil city has a complex configuration in plan. Taking into account that the further construction is located on the filled soil, the design of the foundations in the form of a continuous flat plate was adopted for all further construction, which significantly reduced the pressure on the soil. To reduce the consumption of concrete and the weight of the plate used expanded in plan polystyrene foam. A more regular structural system is the foundation slab, designed for the construction of a resort hotel in Morshyn village of Lviv region. In order to reduce the consumption of concrete and insulation of the basement floor was designed a solid foundation slab with rectangular foam polystyrene inserts in plan. The need of strengthening the foundations of the building on Lemkivska street in Lviv is connected with building vertical extension, which significantly increased the load on the foundation and pressure on the soil. In view of the insignificant width of the foundations base and the filled soil below them, the main option was to strengthen the foundations by arranging a solid monolithic slab with inserts, which was brined under the existing foundations. The use of polystyrene inserts in reinforced concrete foundation slab allowed significantly (by 28,2–30,7%) to reduce consumption of concrete and to arrange a warmer basements floor during the construction of new buildings and in the reconstruction of existing buildings.
