The article uses a method of research and determination of damage and defects ofstone structures. This method provides elimination: the presence of cracks, their length, and width ofthe opening, the presence of defects in the brickwork, the presence of erosion in the brickwork, thedisplacement of arched and arched bridges.To assess the strength of bricks and mortar in masonry, the proposed method was as follows.Places for drilling in brickwork were chosen arbitrarily along with the entire height of the masonry.Drilling was performed perpendicular to the brickwork. The number of places required for drillingcorresponded to the number of samples tested for compression, according to the normative document.To determine the performance properties of brickwork, by following per under regulations in acomplete inspection of buildings, sampling methods used a large number of studies. This problem isespecially relevant for brick buildings to the defects and damages of constructive characterestablished during the inspection which accounting by standard methods does not provide necessaryreliability.The task is complicated if the structure, under the influence of certain operational factors, therewas a change in its stress state, which cannot be estimated by calculation. The structural elementselected for inspection is responsible, which in turn will lead to the destruction of the redistributionof forces and will be dangerous, which can lead to the destruction of other elements and the collapseof the entire system of structures. In this situation, it is recommended to adopt a method that allowsyou to experimentally determine the actual level of stress of the whole element or its individual part.The method was developed primarily for old residential and public buildings (architecturalmonuments) and helps to preserve the original appearance of structures, which does not violate thearchitectural ensemble of the whole house.
