Influence of Reinforcing Composite Mesh on the Strength of Walls Made of Cellular Concrete Blocks under the Action of Static and Dynamic Loads

The results of experimental studies of the strength of masonry walls made of cellular concrete blocks under various force influences are presented. It is noted that the use of walls made of cellular concrete blocks with a density of D400–D600 in seismic areas can significantly reduce the magnitude of the seismic load on the structure. The behavior of masonry under the action of loads simulating seismic actions was studied, taking into account its reinforcement with composite materials based on carbon fiber reinforced polymer (CFRP) and basalt fiber reinforced polymer (BFRP). Data on test of full-size wall samples on the vibration platform, taking into account external reinforcement with carbon fiber tapes, are presented An increase in the seismic resistance of reinforced structures due to the use of composite materials has been revealed. The nature of the destruction of wall panels reinforced and non-reinforced with composite canvases is shown. According to the results of tests of fragments of walls made of cellular concrete blocks using reinforcement composite mesh based on basalt fiber, the effect of its use in axial stretching of masonry was noted. The use of a composite mesh with a 25x25 mm cell based on basalt fiber made it possible to increase the tensile strength of the masonry across the cross section by 28%.
