    Measuring system to monitor deformation of large size structure members
    (2020) Zakharchenko, M.
    About 250,000 bridges in use in the world require inspection and repair, monitoring and control of the condition of the structure. External conditions such as daily change in temperature, change in wind force and direction, rainfall, seismic shocks, and traffic load (number, weight, and speed of motor vehicle traffic on the bridge) are the most significant factors that influence the deformation of the bridge structure. The purpose of this article is to identify the most effective methods and measurement system for monitoring deformations of large structural elements. For the technical realization of this task it is necessary to develop a measuring system that will provide control of the deformation parameters of the bridge structures within the automated deformation monitoring system (ASDM). The use of a measuring system, which includes a laser beam scanner and analog-to-digital converters (ADCs), allows all measurements of deformations of objects of various lengths to digitize the ADCs "linear displacements - time - code", after which the converted information enters the computer. for further processing and storage, or for use in ASDM and others. And the use of ASDM, in turn, will allow you to quickly control the condition of the bridge structures, deflections resulting from the influence of external climatic influences, as well as intensive transport load. The developed methodology and the proposed system of measurement of deformations of large structures are proposed for the first time.
