Application of 3D Laser Scanning for Digitization, Design and Analysis of Multistoried Building

Abstract

Laser scanning is a fast-developing technology, which collects millions of points and creates a framework within a few minutes, generating a 'point cloud' of the structure. Laser scanning is a quite new but rapidly evolving technology that has been reviewed. this research study has used most modern models of laser scanners and their accompanying software that are capable of accurate capture and alignment of point clouds. Consequently, the laser scans have precisely captured the current geometry of each structure, which is irregular in many cases due to inherently complex geometry, anomalies during the original construction, aging, deterioration, and structural damage. As both the exterior and interior of the structure have been scanned, the point cloud became a digital 3D image of the historical building, which can be virtually toured from inside and outside. A 4-story public building was scanned using a 3D laser scanner to determine the architectural and structural drawings of the response to an earthquake. The application of passive control using a damper with the laser scanner has been modelled in this study. The results corroborate that this technique provides the best outcomes for reducing seismic damage collapses.

“…Kurdistan Region, Iraq. Bhatti et al, (2021) scanned a 4-story public building using a 3D laser scanner to determine the architectural and structural drawings of the response to an earthquake. Zhu et al (2010) used MAGER 5006i fixed 3D laser scanner to scan the circumferential cracks in the Longxi Water supply Tunnel.…”
