Deformation behavior analysis of composite structures under monotonic loads based on terrestrial laser scanning technology

A statical experiment of composite structures based on Terrestrial Laser Scanner (TLS) measurement was conducted to investigate the deformation behavior of arch structure. In this paper, laser scanning measurement data of thirteen epochs are collected and data are extracted and processed with MATLAB. How to improve the reliability of composite structural deformation monitoring is one of the key problems in the field of health monitoring. Comparing with the traditional monitoring methods, TLS monitoring has better flexibility and especially in the actual projects. Because some embedded sensors failed after running several years, other means of structural deformation monitoring are required. The goal of this paper is to investigate the feasibility of TLS technology, which is higher efficiency, accuracy and intelligence, to supplement or substitute the traditional monitoring methodologies.
