Monitoring System of a High-Rise Building during Operation

Monitoring of structures during operation is a direct requirement of the current legislation, especially relevant for technically complex structures, which include high-rise buildings. It is important not only for ensuring mechanical safety during construction operation, but also as a tool for reverse analysis of the actual stress-strain state of structures and foundations for compliance with the design calculation forecast, which should ultimately contribute to the development of construction theory and practice. The article is devoted to the organization of monitoring during the operation of the Lakhta Center skyscraper in St. Petersburg. The basis of the monitoring system is a design model of the building that interacts with the base making it possible to give the monitoring an interactive character. Particular attention is paid to the definition of «alarms» that make it possible to signal timely about the occurrence of negative trends helping to eliminate the occurrence of an emergency. It is shown that the calculations for justifying the criteria of monitoring systems differ significantly from the usual calculations when designing. The article defines the features of a workable monitoring system, to which the system implemented in practice fully corresponds. A comparison of the readings set in the design of measuring equipment and design expectations is given. The example of a high-rise building shows how to assign the «alarm» and «accident» criteria to ensure the operability of the monitoring system during operation.
