Grynyova I. STRESS-STRAIN STATE AND RESIDUAL BEARING CAPACITY STONE PILLARS

The object of research is the process of deformation and destruction of eccentrically compressed stone pillars damaged during the operation with different parameters of damage; the purpose of the study is to develop a model for quantifying the carrying capacity of eccentrically compressed damaged stone pillars based on a study of their stress-strain state; methods - collecting, studying and analyzing of reference, mathematical theory of experiment planning, modern methods for measuring material deformations, processing and analyzing experimental results, mathematical and physical modeling of stress-strain state of experimental samples, comparing simulation results with experimental data; results - as a result of experimental and theoretical studies, a computational model of damaged compressed stone pillars was created, which can be used in the practice of construction and reconstruction of buildings and structures, which will allow a rational approach to the issue of strengthening and repairing damaged compressed elements, knowing their residual load-bearing capacity; novelty - the degree of influence of damage factors, as well as the eccentricity of application of external compressive force on the bearing capacity of stone pillars damaged during operation, is determined; experimental data obtained on the work of damaged stone pillars; proposed the calculation of the residual load-bearing capacity of damaged stone structural elements of buildings and structures on the basis of the main provisions of the current regulatory documents; a method has been developed for calculating the load-bearing capacity of masonry structures; implemented - in the practice of reconstruction in the development of the project of overhaul of the building of warehouse number 8 at the address: ul. Customs Square, 1 in the city. Odessa and in the educational process OSACEA.
