ANALYTICAL STUDY OF CROSS LAMINATED TIMBER FEM MODEL WITH ADHESION SURFACE MODELED BY COHESIVE ZONE MODEL UNDER IN-PLANE STRESS

This paper presents a FEM model that can simulate the in-plane behavior of Cross laminated timber (CLT). In the analytical model, the wood was modeled by orthotropic elasticity and the adhesion surface was modeled by Cohesive Zone Model. In order to verify the accuracy of the analytical model, several previous experiments were simulated. Generally, the good agreement between the analyses and all experimental results was shown, and the in-plane behavior of CLT could be simulated.
