Mechanisms for the formation of vertical cracks in the corner zones at the intersection of the exposed walls

The beginning of mass construction of buildings with reinforced concrete frame at the beginning of the twenty- first century required the use of more efficient enclosing structures in the context of heat transfer resistance. The lack of the necessary information on the device sandwich walls led to the fact that mistakes made in the design and construction of laminated structure, were subsequently one of the causes of cracks and destruction of brickwork. The purpose of this article is to examine the vertical cracks in the corner zones of buildings, as one of the typical damage the brickwork. After analysis of the strain-stress distribution of the texture brick layer under different conditions of its interface with the concrete floor, revealed some of the mechanisms of formation of vertical cracks in the corner zones of buildings. We have determined that despite the apparent origin of a similar nature vertical cracks, mechanisms of their formation differ greatly. As a result, we found that the method for selecting the optimum exterior brickwork of protection against damage is necessary to analysis and calculate of structures brickwork, which will minimize the chance of destruction.
