“…Detchev et al reviewed the advantages and disadvantages of using remote sensing methods, such as terrestrial laser scanning and digital close‐range photogrammetry, for the purposes of precise 3‐D reconstruction and the estimation of deflections in structural materials. It is also shown how a low‐cost setup of multiple digital cameras and projectors can be used for the monitoring of concrete beams subjected to different loading conditions by a hydraulic actuator.…”

Deformation measurements are performed periodically to prevent death and injuries in case of the damage or collapse of manmade structures such as dams, tunnels, bridges, high‐rise buildings, and other natural landslide regions. Deformations and displacements in such structures can occur if structures are not built on solid ground and they are subjected to huge static loadings, which causes hazardous shaking due to the motion of the ground beneath. To reduce losses, it is very important to make continuous observations using various measurement methods to detect changes and to analyze the scales of these changes using various analysis techniques. The aim of this study is to determine the behavior of a steel arch bridge under a static load by measuring and analyzing potential deformations and displacements using four different measurement methods. The graphs depicting the result of each measurement method show that the results of the four different measurement methods coincide with each other.

“…On a smaller scale, more specifically of elements which make up a structure (beams, columns, foundations, slabs etc. ), monitoring has been carried out by employing structural instrumentation techniques with the use of deformation sensors, displacement transducers, accelerometers, inclinometers, extensometers, etc., (Erol, 2010) (Detchev et al, 2011) (Díaz et al, 2018) (Kovačič and Motoh, 2019).…”

Monitoring and control of large size civil works was an important and well known application area for topographical and geodetic methods, with a wide range of articles published. However, documented experiences applying precision geodetic methods in monitoring in a smaller scale (structural elements: beams, columns, slabs, etc.) are sparse. The main objective of this study is to evaluate and compare the use of precision geometric levelling technique with instrumentation with displacement transducers (structural instrumentation method) in vertical displacement control in a concrete beam with excessive deformation, being subjected to recovery processes and reinforcement. Although precision geometric levelling is not considered a modern technique in the structures monitoring, it is cost-effective feasible, accurate, and highly precise, with acceptable uncertainties and results, considering procedures normally followed in the processes of recovery and reinforcement related to this type of works. The results have shown that precision geometric levelling is an effective alternative, with remarkable advantages in assembling times and installation, as well as in monitoring post-recovery process of structures (medium and long term), and as the possibility of establishing a correlation between the behaviour of the monitored points. In addition, precision geometric levelling is a valid alternative to be implemented jointly with structural instrumentation techniques, especially where redundancy needs to be obtained in the observations.
