Abstract— The main objective of this paper is to define the fire performance of unprotected Cross Laminated Timber (CLT) floor panel by comparing available experimental results with numerical and analytical analysis. A numerical model of multi-layered CLT panel is implemented in ABAQUS using Finite Element Method (FEM), while analytical analysis based on simplified design method known as the Reduced Cross-Section Method proposed by Eurocode 5, Part 1-2. Mechanical and thermal analysis of unprotected, 5-layer CLT panels is performed to simulate bending test at ambient temperature and during fire condition. Temperature distribution within the cross-section of the slab panel has been investigated and the fire resistance of the loaded timber elements has been evaluated. The overall results obtained from the numerical and analytical analysis show level of agreement is satisfactory as compared with the experimental data.
