| Abstract |
As environmental concerns and the demand for sustainable building materials continue to increase, the use of Cross-Laminated Timber (CLT)
has expanded significantly due to its strength, dimensional stability, and suitability for various construction applications. However, the complex
laminated structure of CLT requires refined analysis methods to accurately evaluate its shear and bending stiffness. Although Finite Element
Analysis (FEA) is widely used to model the behavior of CLT, its complexity and computational cost often limit its practical use during the
elastic design stage. In this study, a 2D plate analysis approach was established to simulate the elastic behavior of CLT panels using a
commercial structural analysis program. To verify the applicability of the proposed model, experimental data from studies in the literature
were implemented into the analysis model. The results demonstrated that the 2D plate model effectively captures the elastic behavior of CLT
panels, with displacement and stiffness errors within 10% for most cases. For panels with span-to-depth ratios below 20, shear deformation
effects were found to be significant and should be considered in the analysis. These findings suggest that the proposed 2D plate analysis
model offers a practical and reliable alternative for the structural design of CLT panels. |
