Structural Stability Evaluation of Existing Buildings by Reverse Engineering with 3D Laser Scanner

In the Fourth Industrial Revolution, research and development of application technologies that combine high-tech have been actively conducted. Building information modeling (BIM) technology using advanced equipment is considered promising for future construction projects. particular, a 3D laser scanner, LIDAR expected to be solution building safety inspections. This work proposes new method evaluating stability scanner. this study, an underground parking lot was analyzed Further, structural analysis performed finite element (FEM) by applying figure geometry data acquired from scan. process includes surveying modeled point cloud scanned building, such as identifying relative deflection floor slab, sectional shape inclination column. Consequently, diagnosis original evaluation criteria. confirms it precise efficient use scanner assessment. paper presents digital cloud-based approach evaluate buildings.
