The influence of nonuniform movement of rubble foundation on bearing capacity of brick walls of a historic building

Purpose: The aim of the work is to determine the bearing capacity of walls and columns of the building during significant movement of its natural-stone foundation on unstable soil.

Methodology: The finite-element model of stress-strain state is developed by using Ing+2021 MicroFe software package.

Research findings: During 168 years of the long-term service since 1854, the negative effect from soil frost-thawing, frost heave of the rubble foundation, and geotechnical influence of the Tom river, provided a significant fluctuation of the water level during low-water and flood periods. The foundation was considerably settled, that disturbed the spatial rigidity of the historic building.

Practical implications: The obtained results can be used to develop recommendations for ensuring necessary spatial rigidity of the brick building via the reinforcement of exterior walls with tensioned steel ties on inter-floor and attic ceilings.
