This research is collecting about the fire regulations and codes for the construction of Cross Laminated Timber of CLT in Europe, North America, Japan, and discussion and research on the structural fire resistance test and fire characteristic execute of the Cross Laminated Timber CLT, and according to the reference manual for fire design and construction of wooden structures, suggestions on the addition and repair of the CLT structure of the Cross Laminated Timber are proposed. It is expected to execute the fire resistance test of 2 sets of CLT floor and 2 sets of CLT wall to discuss for verification. The test specimens used 5 layers of 15cm Japanese cypress CLT (in compliance with JAS regulations) and 5 layers of 12cm Japanese cypress and Cryptomeria (in compliance with JAS regulations) to execute fire resistance tests for the floor and wall for 1 hour and 2 hours. After the CLT test specimen to the fire resistance test, the charring layer is scraped to confirm the charring depth and the charring rate. After the charring layer has been clearing for structural section of the CLT specimens heating surface, and the longitudinal and transverse charring depth values are measured every 10cm. The charring depth and charring measurement rate results are by the Japanese wood charring rate prediction model, it is calculated by the formula and cross-compared analyzed with the charring depth obtained after the practical experiment. Use the correlation coefficients of test data and estimation models to discuss the accuracy of the predictions, and serve as a reference for the design of wooden structures for future reference revisions.
