Abstract

The paper studies an extended five-storey brick building on a pile foundation, subjected to significant deformation. The building reliability is assessed after the instrumented survey. During the building construction and operation, its spatial stiffness is broken with the crack formation in the walls and foundation frame due to an insufficient pile immersion in the gravel layer in difficult engineering and geological conditions. Due to accident technical conditions of the brick walls, the superstructure block is examined in the first phase. The second step includes the examination of the foundation frame and pile using bored pits. The MicroFe software is used for finite element modeling of the stress-strain state of the pile foundation and footing strength of the footing–foundation–building system. The obtained results allow assessing the building reliability and developing recommendations on the pile foundation serviceability.
