The researches of the stress-strain state of the multi-storey administrative building frame with taking into account the pile foundations uneven deformation
Problem statement. The researches purpose is to evaluate bearing capacity of the building frame system and plate-pile foundation with taking into account the deviations in the building constructions from the design parameters and the pile base deformation. Results. Identified the main stress-strain state change regularities in the stress-strain state of the system elements «pile-base - plate grillage - multi-storey reinforced concrete frame» due to uneven deformation of pile groundbase. Conclusions. The obtained results for construction industry significance consists in determining the existing deviations influence from the design parameters on the building constructions, groundbases and foundations bearing capacity. The researches results can be used in the reconstruction projects development for buildings with a significant load increase on the existing load-bearing constructions and groundbases.
