Description of the information service for high-precision monitoring of the composite engineering structures’ displacements and deformations to ensure the forecasting technological emergencies problems’ solution

Abstract

The article discusses the issues of information support for the safety of composite engineering structures (CES), such as railway and automobile bridges, dams, high-rise buildings, objects of operation at space centers, etc. The most effective approach to creating systems for monitoring the CES safe state is the integrated use of data from the ground and space high-precision monitoring tools for the static and dynamic displacements and deformations of the CES design elements. The information service developed by the specialists of JSC “Russian Space Systems” relates to the field of monitoring composite engineering structures, namely for operational monitoring of the complex structural elements’ and unique engineering structures’ state. The services are provided by a measuring complex, which can be included as traditional for this area precision meters of physical quantities and meters that work with the support of global navigation satellite systems. The service identifies the dangerous state of a composite engineering structure, based on an analysis of the dynamics of changes in the CES parameters and scenarios of the dangerous state of a composite engineering structure. The ultimate goals of creating such information services is to provide the data necessary for assessing the mechanical safety of engineering structures, departments and individual enterprises involved in organizing the execution of functions to support the life CES cycles.

Finite element analysis of pitting corrosion on mechanical behavior of E690 steel panel

“…Lightweight and multifunctional materials and structures have become the mainstream design of offshore engineering structures (Rabiee and Ghasemnejad, 2019; Kwon, 2019; Deifalla, 2020; Kalinin et al , 2020). As a typical periodic lattice structure, corrugated metal sandwich panel has been widely used in engineering because of its advantages of simple preparation process, high stiffness and lightweight.…”
