Analysis of the calculation and experimental method for determining the bearing capacity of stone structures

Abstract

The article presents the results of an experimental study of the stress-strain state of damaged stone columns. It includes an overview of the general research methodology and methods for addressing specific tasks. Detailed descriptions are provided of the strength testing methods for individual elements of brickwork, including bricks and cement-sand mortar. The article also introduces the technology for manufacturing and testing the eccentric compression of stone columns of various cross-sections. A matrix of the conducted experiment is presented, which includes levels and varying factors such as the depth of damage to elements, eccentricity of load application, and angle of inclination of the damage front along one of the principal cross-sectional axes. The experiment's results reveal the most adverse factor affecting load-bearing capacity. Additionally, a calculation and analysis of the safety margin are performed based on the examination of the materials used, which are not considered in calculating the load-bearing capacity of the damaged stone column.
