Slab Diflection Analysis using Digital Close-Range Photogrammetry

Mostafa Abdel-Bary EBRAHIM

Abstract: In the construction field, deflections experienced during construction are costly and preventable. However, inspection programs employed today cannot adequately detect and manage deflections that occur on construction sites because current inspection programs are based on measurements at specific locations and times and are not integrated into complete electronic models. Testing and measuring are important examples of determining slabs deflection. Sometimes they require accurate measurements depending on the issue at hand. Close-range photogrammetry is one of the most important and accurate measuring techniques that does not require direct contact with an object. Additionally, most of the procedure for close-range photogrammetry can be carried out in the office. The objective of this paper is to present the use of close-range photogrammetry as a useful and accurate measuring tool for determining and analyzing slabs deflection in the construction field. We have applied close-range photogrammetry to a practical case in a construction site to demonstrate its application to the issues of construction slabs deflections.
