Abstract

Repetitive loading of factory crane girders causes deformation and/or failure. In the presented method, LiDAR-points over one face of a girder are processed to create deformation maps of panels: web area between stiffeners and flanges. Web surface profiles at top, mid and bottom locations are created by matching a standard I-section template to point data. Root mean square error (RMSE) at each girder slice is computed by comparing the nearest girder points and inflection points from the template. The girder point with the lowest RMSE is selected as the correct match and three locations are identified.
