| Abstract: | This article combines the tensioning process of a prestressed beam on the roof of a certain factory building to monitor the main control section stress, reverse arch value, elastic compression deformation, anchor deformation, internal shrinkage value of steel bars, and cracks under local pressure. The research results of this article provide important basis for controlling the tensioning effect of prestressed beams and ensuring construction quality, which can be used for reference by similar projects. |

| Keywords: | Construction monitoring Tensioning process Prestressed beams Post tensioning method Bonded |
