The Belgrade Fair represents one of the most successful realizations of Serbian architecture and structural engineering. It was constructed between 1954 and 1957, based on architectural and urban planning design by Milorad Pantović and structural design by Branko Žeželj and and Milan Krstić, as a modern complex of three exhibition halls with recognizable domes. Hall 1 is the largest building of this complex, protected as cultural heritage. Its specific solution represents an outstanding structural realization, while its dome still holds the Guinness record for this type of structure. The IMS Institute constantly monitors the condition of the Belgrade Fair buildings, and through expert support provides safe and functional exploitation of exhibition halls. The paper showcases the methodology and results of inspection and assessment of condition of the Hall 1 structure after almost 70 years of use, including realized testing of prestressing force in cable wires in ring girder bearing of Hall 1 dome.
