Force Transfer around Openings in Cross-Laminated Timber Shear Walls
Publication: Journal of Structural Engineering
Volume 143, Issue 4
Abstract
This paper presents a study on force transfer around openings (FTAO) in cross-laminated timber (CLT) shear walls. To elucidate the load transfer mechanism in CLT walls, this study used finite-element models to study five different CLT shear wall configurations. The effect of uncertainty in the behavior of connectors in the wall over its force-deformation behavior and design transfer force was also studied. In a coupled-panel wall, the presence of an opening decreased the strength and stiffness of the wall and tie-rods were provided as reinforcement to limit the deformation between the panels in the wall and to improve its strength and stiffness. The models presented here provide a tool to determine the transfer force in a CLT shear wall for design of tie-rods and develop a better understanding of load distribution within the wall.
