Problem of the crack formations in the area of intersecting loadbearing walls built with AAC masonry unit

In the paper the attempt of determining the influencing factors of the formation of typical cracks in the area of loadbearing walls corner made of ACC masonry unit was made. Numerical calculations were conducted and they showed that with extreme self-weight loads, imposed loads, environmental and rheological loads the corner of the walls was exposed to the damage. At different level of loads and different geometry of walls the size of shrinkage deformations, by which the crack formations in the area of intersecting loadbearing walls won't take place was given.
