This paper deals with laboratory measurements of deformations in the place exposed to local load caused by pre-stressing. The measurements are made at the masonry corner built in the laboratory equipment. The laboratory equipment was designed at Faculty of Civil Engineering VSB-TU of Ostrava for measurement tri-axial stress-strain conditions in masonry. In this masonry corner two pre-stressing bars are placed. These bars are in different height and are anchored to the anchor plates, which transfer pre-stressing forces to the masonry. The masonry was pre-stressed in the both directions. The specimen for laboratory testing is performed in the proportion to the reality of 1:1.
