Implementation of the Continuous Monitoring System for Technical Condition of the St. Petersburg Arena Stadium Sliding Roof

Modern engineering facilities are unique objects in a single instance with a complex architecture and no less complex technical features. Such objects include the St. Petersburg Arena stadium built in 2016 in Saint Petersburg City. In addition to all the architectural delights, the stadium is also unique due to the decision to erect a sliding roof in order to protect the field and fans from the wind, rain and snowfall that are common in the region. The roof is a complex structure that requires constant monitoring of its technical condition. The system of continuous monitoring of technical condition of the roof structure of St. Petersburg Arena stadium is described in this paper. The uniqueness of the design was predetermined by the careful analysis of the measuring controllers arrangement in the computer model of the diagnostic object. The work describes the object under test in general and the sliding roof apart, as well as the connection points of the measuring controllers sensors indicating the required number of them (strain gauge, inclinometer, deflection sensors, and a weather station are used). The peculiarity and novelty of the problem being solved is that there are only four stadiums with a sliding roof in the whole world, and it is the only such construction in the Russian Federation. The technical solutions presented by the authors allow the transfer of monitoring results to the city's situation center, which in turn increases safety level and reduces the emergencies risks at the diagnostic site.
