Terrestrial Laser Scanning-Based Deformation Analysis for Arch and Beam Structures

Abstract

Nowadays, with the assistance of the high accuracy terrestrial laser scanning (TLS) measurement techniques, the mechanics analysis of structures could be better understood. This paper has a comparative analysis of arch and beam structures in terms of deformation behavior in loading experiments. The goal of this paper is to discover the potential value of the different structures in the architecture through the investigation of the anti-load capacity of the arch and beam structures. This paper is focused on the comparison of load-displacement relation between arch and beam with static load experiment, which is based on TLS techniques and surface analysis method. The innovation is that we try to reveal the partial area changing rules named “partial area analysis,” which is a new method to investigate the deformation behavior of structure. It is exposed that both arch and beam structures in the loading progress would suffer three stages, which are steady, developing, and fracture. Furthermore, considering the effect of pre-stress, steady stage would last longer, and developing and fracture stages would be hysteretic.
