Performance based design for mass timber structures in fire– A Design Example
- 2018
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Recent fires in tall buildings occurring in for example London, Dubai, Sao Paulo and Tehran evidence the risk of high consequences of fires in tall buildings and difficulties for fire service interference in case of large fire spread. In order to reduce the risk of deadly and large damage fires in especially tall buildings it is of importance to limit fire spread and avoid collapse .It was previously indicated that prescriptive fire safety regulations are mostly based on experience rather than on scientific facts. Therefore, the application of regulations for less conventional buildings, such as tall timber buildings, is questionable. In contrast with prescriptive requirements, performance based requirements, such as a requirement for a building to withstand a full fire without effective fire service interference, require accounting for the design and the function of the building. Multiple performance based methods for the fire safety design are available for buildings with conventional structural materials, i.e. steel and concrete. For buildings with timber as a structural material performance based structural design is rarely applied due to lack of methods available.The number of tall buildings with timber as their main structural material is increasing globally, which involves new fire safety challenges. In contrast with more conventional structural materials for tall buildings, timber can fuel the fire and influence its duration and severity. A number of previous experimental studies have shown that enough contribution of exposed timber to the fuel of a fire can result in continuous fully developed fires. Additionally, events that lead to increased combustion, such as sudden exposure of initially protected timber or bond line failure in glued timber members, can lead to fire regrowth after a period of decay. Without effective sprinkler or fire service interference, these fires would eventually lead to collapse, which can lead to potentially unacceptable consequences in very tall buildings.

IAFSS agenda 2030 for a fire safe world
- 2019
-
Ingår i: Fire Safety Journal. - : Elsevier BV. - 0379-7112. ; 110

Tidskriftsartikel (refereegranskat)abstract
- The International Association of Fire Safety Science (IAFSS) is comprised of members from some 40 countries. This paper presents the Association's thinking, developed by the Management Committee, concerning pressing research needs for the coming 10 years presented as the IAFSS Agenda 2030 for a Fire Safe World. The research needs are couched in terms of two broad Societal Grand Challenges: (1) climate change, resiliency and sustainability and (2) population growth, urbanization and globalization. The two Societal Grand Challenges include significant fire safety components, that lead both individually and collectively to the need for a number of fire safety and engineering research activities and actions. The IAFSS has identified a list of areas of research and actions in response to these challenges. The list is not exhaustive, and actions within actions could be defined, but this paper does not attempt to cover all future needs.

Euroclass predicitons for developing wood based products with improved fire performance
- 2010

Ingår i: Interflam 2010: Proceedings of the twelfth international conference. - : Interscience Communications. Interscience Communications.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Fire performance is one of the main obstacles to an increased use of wood based products in buildings. Fire retardants may considerably improve the fire properties of wood based products. Fire retardant treated (FRT) wood based products can meet even the requirements for Euroclass B, whereas untreated wood products belong typically to Euroclass D. Simple rules for predicting the Euroclass of wood based products on the basis of cone calorimeter data have been developed. These rules can be used in product development of FRT wood based products.

Fire Safety in Timber Buildings : Technical Guideline for Europe
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This is the very first technical guideline on the European level for the fire safe use of timber structures and wood products in buildings. It aims at providing the highest scientific knowledge and covers the extended use of European design codes and standards, practical guidance, examples for fire safe design and principles of performance based design. The guideline presents information for architects, engineers, educators, regulatory authorities and building industry. The guideline is focusing on structural fire design by providing the latest detailed guidance on separating and load-bearing functions of timber structures under standard fire exposure. Reference is made to the Fire Part of Eurocode 5 and, where new knowledge is available, to other references. Depending on national regulations, some of the new design methods may need agreement by the competent authority. This new information will be potential input to the next revision of the Fire Part of Eurocode 5. The guideline also includes information on reaction to the fire performance of wood products according to the European classification system. The importance of proper detailing in building design is stressed by practical examples. Active measures of fire protection and quality of construction workmanship and inspection at building sites are presented as important means for fulfilling the fire safety objectives. The guideline has been developed within the European research project FireInTimber (Fire Resistance of Innovative Timber structures). Leading experts and researchers from nine European countries have been participating and guarantee its quality and relevance. The project has been initiated by the European initiative BWW Building With Wood under the umbrella of the European Wood Industries CEI Bois. It is sponsored by the European wood industry in cooperation with national funding organisations within the WoodWisdom-Net Research Programme.
