Abstract
The experimental study on evaluation of seismic resistance of the large-scale model of a two-story fragment of brick building
from ceramic bricks on cement mortar was conducted. The dynamic testing of the prototype was carried out on the two-component
vibrio plat form, where seismic impacts with the intensity of 7 to 9 according to MSK-64 scale were modelled. During the tests the
constant load on floors – 4,5kH/m2 was simulated using dynamic forces to the prototype were simulated. Different options for
strengthening of load-bearing brick walls concrete blocks. The dimensions of the two-storey fragment are 2,3x × 1,56 × 3,0m. Using
scrims from carbon fibre the slabs at each floor were combined into a single hard disk. During the tests, the horizontal and vertical
with composite fabrics, scrims and nets, were considered. Upon the nature of the hysteresis curves the zones of elastic performance
of masonry walls at the moment of cracks and destruction were determined. The optimal schemes of brick walls’ strengthening
were proposed with the use of ribbons, scrims and nets from carbon cloth. The possibility to increase the stiffness of the slabs disk
with composite materials was shown.
