Abstract

Terrestrial laser scanner can remotely obtain 3D coordinate data of a structural member without installation of sensors or reflective targets on the structure. In this paper, to overcome the limitation of the conventional measuring system based on strain sensors, relative changes in 3D coordinate data obtained from a laser scanner are used for estimation of the maximum stress in beam structures in a building. The estimated stress from 3D image data was compared with the maximum stress measured directly from electrical strain gages.
