| Abstract |
In a previous paper, displacement and deformed shape measurement model is proposed for structural monitoring using terrestrial LiDAR. In this paper, the proposed model is applied to displacement measurement of simply supported steel beams subjected to a point load. The performance of the proposed model is investigate by comparing the displacement obtained from the model and displacements directly measured from various measuring devices such as electrical strain gages, fiber optic senors and LVDTs. For the assessment of stresses in a beam, stresses induced in the beam are calculated using the displacement measured from proposed model and the stresses also are compared with those from the electrical strain gages and fiber optic sensors. |
