Defects in a dilapidated building resulting in loss of bearing capacity of supporting structures

This article is devoted to assessing the effectiveness of technical inspection of the condition and the degree of influence of various factors on the reliability of buildings. Technical inspection of the condition of buildings and structures is an important procedure for making decisions about the suitability of the structure for its further operation. Technical inspection should be carried out by specialized accredited organizations that have the necessary expertise and equipment. Adverse environmental factors, poor quality of construction and installation work and general physical deterioration of the building have a direct impact on the safety of people staying in it. The object of the survey was the building of a secondary school in the Karaganda region. Visual and instrumental inspection was carried out at the object, including determination of technical condition and damage categories by shock-pulse method and geodetic surveying. According to the results of the inspection of the object the conclusion of improper condition of the load-bearing structures belonging to category IV, i.e., pre-emergency state of the structures was assigned.
