The Fire Performance of Exposed Timber Panels
نویسنده
چکیده
Cross-laminated timber is increasingly being used in the construction of high-rise buildings due to its simple manufacturing system. In term of fire resistance, cross-laminated timber panels are promoted as having excellent fire resistance, comparable to that of non-combustible materials and to heavy timber construction, due to the ability of thick wood assemblies to char slowly at a predictable rate while maintaining most of their strength during the fire exposure. This paper presents an overview of fire performance of cross-laminated timber and evaluation of its resistance to elevated temperature in comparison to homogeneous timber panels. Charring rates for cross-laminated timber panels of those obtained experimentally were compared with those provided by Eurocode simplified calculation methods. Keywords—Timber structure, cross-laminated timber, charring rate, timber fire resistance.

Summary of the fire protection foundation report - fire safety challenges of tall wood buildings
Buildings constructed from engineered timber are becoming more prevalent globally as building designers, owners and architects realize the sustainability opportunities with timber construction and the overall aesthetic of a completed timber building. As timber buildings are planned to be taller than many model codes permit, the National Fire Protection Association (NFPA) Fire Protection Foundat...
متن کاملEurocode 5 design in comparison with fire resistance tests of unprotected timber beams
It is generally recognized that heavy timber in fire conditions demonstrates high structural performance. Exposed timber chars which functions as an isolative layer which protects the inner material from heat and loss of load bearing capacity. Char has no significant strength, and therefore, as the char layer grows, the load bearing capacity of the timber member reduces under sustained fire con...
متن کاملFire Safety Engineering – Opportunities and Challenges for Timber Buildings
The combustibility of timber is one of the main reasons that many building regulations strictly limit the use of timber as a building material. Fire safety is an important contribution to feeling safe, and an important criterion for the choice of building materials. The main precondition for an increased use of timber in buildings is adequate fire safety. This paper reviews the opportunities an...
متن کاملFire resistance of FRP reinforced glulam beams
Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...
متن کاملTemperature Prediction in Timber Using Artificial Neural Networks
Neural networks are a powerful tool used to model properties and behaviour of materials in many areas of civil engineering applications. In the present paper, the models in artificial neural networks for predicting the temperatures in timber under fire loading have been developed. For building these models, training and testing using the available numerical results obtained using design methods...
