This paper presents the fire performance of unprotected Cross-laminated timber (CLT) floor panel by comparing available experimental results against numerical and analytical analysis. A numerical model of multi-layered CLT panel has been developed using Finite Element (FE) Method. Temperature distribution within the cross-section of CLT panels was investigated. The charring rates for CLT panels obtained from the numerical model were compared with experimental results and those provided by Eurocode simplified approach. The falling off of the charred layer of the CLT panel has also been investigated using the FE modelling. The results show that assuming the immediate falling off of charred layer would happen when the interface between the layers has reached 300°C could lead to consevative prediction.
