A comprehensive inspection and technical assessment of the roof building structures of the industrial building was carried out in order to determine the possibility of installation photovoltaic panels on the roof of the building. The work included an analysis of technical documentation, visual and instrumental inspection of structures, verification calculations.
During the visual inspection, the structural features of the building were clarified, the condition of the joints of elements and structures and areas with damage and defects were identified. Based on the results of the visual inspection, the categories of the technical condition of the structures were ascertained.
Instrumental researches of building structures was performed using non-destructive testing methods and included determination of concrete strength by ultrasonic method for columns, trusses, and roof slabs. No changes in the physical and mechanical characteristics of the concrete of the building's structures were detected compared to the design data. Reinforcement parameters were not determined by additional devices, as they were performed by direct measurements due to the exfoliation of the protective concrete layer.
Verification calculations were performed for a service life in the range of 3-60 years. It has been established that the load-bearing capacity for roof structures with 13-93 series slabs when installing photovoltaic elements is ensured only when the service life of the building is limited to 3 years.
Based on the results of the inspection, recommendations were developed for restoring the technical condition of load-bearing structures and the possibility of operating structures with 13-93 series slabs after installing a rooftop solar power plant.
