Deformation monitoring of typical composite structures based on terrestrial laser scanning technology

This paper focuses on the presentation of new possibilities for surface-based measurement techniques and their applicability in the deformation analysis of arched structures. The goal of this paper is to investigate the difference of load-displacement relationships between arched and beam structures though a static load experiment based on high accuracy TLS measurement techniques and the surface analysis method. In this paper, we try to reveal the influencing mechanism of 'prestressing-like' force and interpret why arched structures can withstand a surprisingly greater load than beam structures under the same conditions.
