Structural Response of CLT Bridge Decks to Heavy Vehicle Loads: A Serviceability Evaluation
https://orcid.org/https://orcid.org/0000-0001-5677-6324
Timber is widely recognized as a construction material of choice, owing to its numerous advantages, including its sustainability and abundance in large parts of the world. Although timber is frequently employed by the construction industry for buildings, its usage in modern bridge structures has remained limited. This research investigates the structural performance of cross-laminated timber (CLT) decks for bridge applications. For this purpose, CLT deck made of Douglas Fir North was fabricated to full-scale but with some reduced width dimensions. The deck was then tested under static and fatigue loading conditions. The experiments evaluated various structural response features, including the bending stiffness, interlaminar properties between the panels, and elongation characteristics from the applied vertical forces, representing heavy vehicular loads equivalent to the design loads expected on a typical short-span bridge. The results demonstrate the promising performance of CLT decks, exhibiting excellent structural performance compared to design standards. Overall, this research addresses a knowledge gap by providing valuable information for CLT bridge deck design and optimization, addressing the lack of modeling guides, and offering recommendations to meet standard requirements. Moreover, it emphasizes the environmental benefits of using timber sourced from sustainable sources, which is feasible in areas that have an abundance of such resources.
