These are the control of the vibrational properties in the structure, Yang at al. (2023), Liao and Chiu (2019); the assessment of deformations using distributed fiber-optic sensors, Ye at al. (2014), Costa and Figueiras (2012); laser scanning methods, Jia at al. (2021). The composition and principles of operation of each monitoring system are individual and are determined by the properties of the object and the tasks set. However, most of these systems are aimed at controlling either the static or dynamic properties of the structure. The approaches we developed earlier, Shardakov at al. (2016), (2018), (2020), allow us to design deformation monitoring systems covering a wide range of deformation processes, from quasi-static to dynamic. 2452-3216 © 2023 The Authors.

The monitoring object is a metal structure 64.350 m high, which ensures the lifting of ore from the mine and its transfer to the factory for further processing. Its deformation state is determined by the loads associated with the operation of technological equipment, the impact of environmental factors and the interaction of the metal structure with the soil and the concrete head of the skip shaft. The developed monitoring system is aimed at preventing accidents caused by structural damage caused by the impact of technological loads and environmental influences. The current state of the object is monitored using several blocks of primary sensors distributed over the key points of the structure. These are a vibration control unit, a system of strain gauges, a hydrostatic leveling system and a unit of inclinometric measurements. The website of the monitoring system displays information about the history and current values of main deformation characteristics of the structure and visually compares the current data with acceptable values. The developed system is significant not only from a practical point of view; it also contributes to a deeper understanding of the deformation processes that develop during the operation of similar structures. © 2023 The Authors.

Introduction The creation of large-scale engineering structures and complex buildings is now increasingly accompanied by their equipping with automated systems for monitoring the deformation state of the object. The presence of a monitoring system is one of the factors that ensure the reliability of the structure and the durability of its operation.
