FIRE RESISTANCE TESTS ON CROSS-LAMINATED TIMBER FLOOR PANELS

摘要

Cross laminated timber (CLT) is an innovative building product currently gaining popularityrnin countries around the world. However, there is little published information available regarding itsrnperformance in fire. The focus of this research is on a series of eight medium-scale CLT fireresistancernfloor tests. Parameters such as charring rates, deflection, gypsum board protection andrnadhesive performance, as well as the overall fire resistance of the floors when subjected to bothrnstandard and non-standard fire exposures were evaluated. The results compare favourably to recentrnstandard full-scale CLT floor tests and demonstrate that CLT panel assemblies can be designed tornpossess a fire-resistance that complies with building code requirements. The additional firernperformance data provided from the results of these tests will help facilitate the incorporation of CLTrninto design standards and building codes.
