USING LASER SCANNING FOR LARGE-SPAN STRUCTURES MONITORING
The articles gives the review and analysis of normative and scientific literature was reviewed, and various options for monitoring large-span structures. It provides the technique of monitoring large-span structures based on the materials of laser scanning. The estimation of the accuracy of combining the scans and the accuracy of determining the marks on various elements of the object were performed. Features of monitoring during construction are determined. It was revealed that the deviations between the series of measurements correlate not only with changes in load on the structure during construction, but also with changes in the ambient temperature. Analyzed the changes that occurred during the monitoring during the construction, identified different types of deformations of the beams of the dome. The tasks of monitoring large-span structures that need to be solved in the context of the introduction of modeling and BIM-technologies are considered.
