Research on the Application of an Information System in Monitoring the Dynamic Deformation of a High-Rise Building

Abstract

With the acceleration of urbanization, there are increasingly more high-rise buildings in cities. In turn, high-rise building collapse accidents occur frequently. The causes of the danger, in addition to the extremely severe stress, are predominantly due to the long-term role of unstable factors, resulting in an unrecoverable internal structure. Therefore, it is advisable to monitor the dynamic deformation of buildings to prevent accidents. However, there is no particularly mature application system on the market to enable this monitoring, so our research group has carried out a long-term research in this field. This paper introduces the design of a set of practical information systems by using information technology and the principle of close-range photogrammetry. The system used the photographing scale transformation-time baseline parallax (PST-TBP) method to analyse image data collected with a digital camera, implement close-range photogrammetry, and input the image data into a computer. A building deformation diagram is obtained using our own software. The associated deformation curve can clearly reproduce the building deformation trend to monitor the building health. We conducted many laboratory simulation experiments to verify the information system, and the verification results prove that this process is rigorous. To apply this information system to a real-life scenario as soon as possible, we further studied its application to high-rise buildings, improved the system by using data and experience obtained by monitoring the tallest local building, and achieved good results. Finally, combined with the development of current intelligent technology, directions for system improvement are explored.

The Dynamic Displacement Monitoring Method Using Unmanned Aerial Vehicles Based on Digital Close-Range Photogrammetry

“…Using the digital close-range photogrammetry technology to monitor the dynamic deformation of buildings can achieve high frequency, multi-point, and contactless observation and has been successfully applied to Bridges [3,4], shuttle steel shelves [5], Masonry Walls in Seismic Oscillation Outdoors [6], Steel structure building [7], super high rise building [8], and so on.…”

Monitoring Dynamic Deformation of Building Using Unmanned Aerial Vehicle

“…Photography, as a noncontact measurement technology, has attracted more and more attention in the past decades, mainly because of its nondestructive imaging characteristics of high precision and sensitivity. Some scholars have successfully applied photogrammetry technology to the deformation monitoring of engineering structures such as steel towers [2], bridges structures [3], masonry structures [4], and so on [5][6][7].…”
