DIAGNOSIS OF USEFUL USEFULNESS OF BUILDING STRUCTURES AS A PREREQUISITE FOR CONTINUING THEIR LIFE CYCLE

Abstract

Normative documents regulate the periodic inspection of buildings and structures or their parts in order to establish their technical condition at the time of the inspection to ensure further reliable and safe operation. The result of the inspection is a technical report with conclusions and recommendations on methods of eliminating the identified defects or structure damages.
Usually, during the preliminary visual inspection of the building structures the presence of damage defects is established and the need for additional special inspections with the use of special equipment.
To detect structural defects in the form of inhomogeneity of the material, reducing its strength, cavities and cracks in the structures, reinforcement parameters (diameter, pitch, thickness of the protective layer), etc. use mechanical, acoustic, magnetic, radiation, electric, electromagnetic, visual etc. methods. The article presents the features of each method and devices that are commonly used in Ukraine and abroad (their principles of operation, features of use and capabilities)..
Methods for determining the humidity of concrete are given. Examples of using digital portable microscope and mini camcorder. Modern methods of inspection of structures of highrise buildings and structures for detection of defects and damages are analysed.
Experience of inspections of building structures shows that during inspections it is necessary to pay attention to even the smallest damages and to consider action of all possible factors. After all, a wellperformed survey will allow you to choose the right and rationally justified methods of repair and restoration work.
