Setting the problem of designing monitoring systems for engineering structures and methods of its solution

Abstract

The unprecedented construction of large-span, high-rise and technically complex Olympic facilities in a very short time sets the goal of ensuring the engineering safety of the facilities being built. A necessary condition for its solution is a well-functioning system of continuous monitoring the state of load-bearing structures. It should be capable of identifying unacceptable deviations in the operability of the structure (reducing its reliability) and notifying operating services in a timely manner. The research is devoted to designing such systems. The research subject of the study is a set of requirements for monitoring systems for engineering structures. The feed data for the conducted studies was information about accidents that occurred at constructional projects with various purposes. Analysis of monitoring tools and controlled parameters was used as a research method. The paper investigated some of the existing monitoring systems. The following global monitoring tasks are formulated: what to control; how to control; controlled parameters.

Ultrasonic Sensors Enabling Early Detection of Emergency Trends and Analysis of Structure Inclination and Stability by Means of Highly Accurate Level Measurements

“…At different stages of the life of the structure, we can distinguish diverse classes of models characterized by different accuracies and complexities. At the design stage, when building the model, we mainly rely on assumptions regarding the materials, soil and weather conditions, as well as the loads that will affect the object during construction and operation [ 23 ].…”
