STRESS-STRAIN STATE DAMAGED IN THE OPERATION STONE PILLAR

Abstract

Based on the analysis of scientific and technical literature and preliminary studies, an experiment was planned on three the most significant factors influencing the residual bearing capacity of damaged stone pillars of a rectangular cross section, namely: depth of damage, angle of inclination of the front of the damage on one of the main axes of the intersections and eccentricity.

To measure the deformation of the masonry, indicators such watch uv-10 point values of 0.01 mm were used. In the laboratory of OSACEA, 15 samples were constructed and tested.

Results of full-scale (laboratory) experiments revealed effects on the carrying capacity of each of the selected factors and mutual influence factors.

Laboratory tests of the test samples allowed to determine the effect of input fracture factors on the bearing capacity and to describe the deformed state and experimentally determine the value of the destructive effort.

According to the estimated damaging load, the greatest impact on the bearing capacity gives the depth of the damage at the intersection of the pillar.
