Description	Due to underground mining and construction of tunnels and collectors in urban areas terrain subsidence occurs with characteristic effects on building structures. In affected areas it is often necessary to detain affected structure with additional pre-stressing of walls and foundations. Pre-stressing masonry is one of the most common and concurrently the most effective method redevelopment. At Faculty of Civil Engineering was constructed laboratory equipment for closer examination of the behavior of tensioned masonry. Specifically for measuring the deformation of brick corner mainly around the anchor plates that used for transmission of tensile forces into 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. 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.
