Abstract
This study explores the direct conversion of point clouds (PC) into as-built wireframe models with two-node elements for the digital twin creation of structures consisting of beams and columns. The process involves capturing PC data via an autonomous robotic platform and analyzing it to identify the geometrical properties of structural frames. For example, ceiling and ground planes align with the Z-axis, while walls align with the X or Y-axis. The study also uses the OpenSeesPy package for physics-based analysis, demonstrating the method’s application in robotic inspection. The study was validated using a four-story mass timber structure as a case study, and the results showed an average error of 7.5% in the frequency of vibrational modes.
