| Description
| - Pre-stressing of masonry is one of the most widespread building/facility reconstruction methods. In the Czech Republic it is very successful, especially in the Moravian-Silesian Region, which is subject to a considerable amount of disturbances of buildings/facilities due to undermining. Pre-stressing in masonry can be achieved by means of steel wire ropes or rods. These steel elements are inserted into the pre-milled grooves, which may be in the external or internal wall face. The ends of the steel elements are clamped into steel angles or special anchors. In these reconstruction methods it is necessary to follow the pre-stressing procedures and technologies. It is important to properly select the pre-stressing anchoring system, appropriate layout and arrangement of pre-stressing wires, pre-stressing procedure and dimension of pre-stressing forces in the individual wires. This contribution deals with experimental measurements of deformations in the place exposed to local load caused by additional pre-stressing. The measurements are taken on a masonry corner built in the laboratory equipment. This laboratory equipment was designed at the Faculty of Civil Engineering VSB – TU Ostrava for measurement of the tri-axial stress-strain conditions in masonry. Two pre-stressing bars are placed in this masonry corner. These bars are at different heights and are anchored to the anchor plates, which transfer pre-stressing forces to the masonry. The specimen for laboratory testing is performed at the actual proportion of 1:1. Mathematical modeling of the brick corner is based on the finite element method using ANSYS software and then the results are compared with results of the laboratory tests. On the basis of these results it should be possible to improve the models and come closer to achieving an accurate and at the same time, simple procedure for the design of pre-stressed masonry.
