CARBON FIBER REINFORCED LAMINATED TIMBER BEAMS STUDIED USING VIC-3D DIGITAL OPTICAL SYSTEM
Abstract
The paper presents results of experimental research carried out into the static bending of reinforced laminated beam. The beam is reinforced with carbon tape placed in the two interlamellar bottom layers. Tests were carried out on a hydraulic press. Deformations and displacements online measurements are provided by the VIC-3D digital optical system based on the principle of correlation between digital stereoscopic images. Linear and shear strains are determined with the frequency of 1 Hz. The obtained images of the stress distribution of the visible beam surface reflect the stage of elastic and elastoplastic deformation. The possibility of using the VIC-3D digital optical system for determination and destruction of laminated beams is shown in this paper.
