INVESTIGATION OF THE ROOF COLLAPSE CAUSES OF INDUSTRIAL BUILDINGS.

Increasing the share of industrial production in the economy entails the  introduction of new and reconstruction of old industrial areas.  However, often, both new and reconstructed industrial buildings have recently been operated incorrectly, with a high probability of collapse. Topical issues on reducing the danger of an avalanche-like collapse of the roofs in the industrial building are considered. The causes of emergency situations and measures of its prevention are indicated. Nowadays, there are many buildings in Ukraine erected from the early 20th-century until 2006 (the year when the DBN B.1.2-2: 2006 was released). These buildings have unacceptable structural schemes, snow load schemes and coefficients that are not considered in DBN. Obviously, the owners do not want to demolish these buildings, so that the designer is obliged to eliminate the inconsistencies found during the examination of the building structures. In particular, it is necessary to design the new or strengthen existing structural elements in accordance with the requirements of the relevant building codes in Ukraine if they are available of course. The current article mentions that not all cases are considered in DBN. Therefore, it is necessary to consider other schemes of snow loads and the corresponding factors, which will be prescribed for existing reconstructed buildings at the legislative level.
