Determination of the Effective Width of Cross-laminated Timber Rib Panels Using Digital Image Correlation

Year: 2023

Type: conference-paper

Abstract: The effective width of cross-laminated timber rib panels is analysed.The floor system consists of crosslaminated timber plates rigidly bonded to glued-laminated timber ribs by means of screw-press gluing.Ultimate-load tests were performed on four different cross-sections.Digital image correlation was used to visualize and monitor the strain distribution on top of the cross-laminated timber plates at midspan.The longitudinal strain distributions along the crosslaminated timber width were obtained for the determination of the effective width.The experimental results are compared to numerical results of a finite element model and to Eurocode 5 estimations.The longitudinal strain distributions show good agreement and confirm digital image correlation as a suitable measurement technique.
