Peter the Great St.Petersburg Polytechnic University, 29 Polytechnicheskaya st., St.Petersburg, 195251, Russian Federation
This article examine the causes of crack formation in the exterior layer multilayer enclosing structures, on early terms of operation (from 3 to 5 years). The problem is investigated on a concrete example of the existing residential building to St. Petersburg. We explore the cracks in the zone interwindow belts and partition. For explore this question used methods such as: analysis of the experience, visual inspection, the experimental methods in laboratories, numerical modeling in the software package ANSYS. As a result of visual examination of sediment soils are not detected. According to the results tests of a selected samples bricklaying, compliance of its durability to existing rules - is defined. Identified a number of causes of crack formation. Also, a number of recommendations is developed for the design, to avoid similar problems on early terms of operation.
