Fire Resistance in Timber
Timber structures are able to offer an abundance of benefits in the design of construction industry. They offer a quick, cost effective and alternative to other construction materials, and perhaps most importantly in todays climate, provide one of the greener construction alternatives (especially if ethically sourced, providing a low carbon and effectively renewable building material). However with this choice, designers need to ensure they fully understand the risks associated with timber, with fire protection being a key aspect of this.
This course will provide an overview of some of the key technical considerations those involved with timber structures should consider in relation to fire protection. Several areas will be covered leaving delegates with a more rounded appreciation of fire resistance including the design of key elements, and a preview of what the next generation of Eurocode 5 will look like.
10:00 - 11:30
Design of linear members
Fire design of timber members consists of determination of char layer and taking the effect strength loss in the heated zone into account. This lecture will describe the general procedure for fire design of timber members and specifically design of glulam beams and columns in standard fire according to EN 1995-1-2. Design example will be given.
12:00 - 13:30
Design of timber frame assemblies
Fire design of timber frame assemblies is more complex compared to linear members. Due to the relatively small cross-sections, timber members can be more effected by fire and the protection by claddings and cavity insulation is important. This lecture will describe the procedure of fire design of timber frame walls and floors with and without cavity insulation. Design methods for rectangular cross-sections and I-joists will be presented according to EN 1995-1-2. Design example will be given.
14:30 - 15:30
Design for separating function
Fire resistance of separating walls and floors can be assessed by tests or by design method. This lecture will introduce a Separating Function Method that is based on summarizing contributions of each layer to the overall fire resistance of the structure. The method is published in the European Technical Guideline Fire Safety in Timber Buildings and will be added to the next version of EN 1995-1-2. Design example will be given.
16:00 - 17:00
News about the next generation of Eurocode 5
All Eurocodes are currently under revision. This lecture will explain the main coming changes and improvements of Eurocode 5 Part 1-2. Description of the procedure for revision will be shortly explained.
About the Lecturer
Alar Just is a professor of structural engineering at Tallinn University of Technology and a researcher at RISE Research Institutes of Sweden. He completed his dissertation on fire resistance of timber frame assemblies in 2010. From 2010 he has worked as a researcher at RISE Research Institutes of Sweden where his research is related to fire resistance of timber structures. He has conducted more than 200 fire tests and is currently supervising 3 PhD students in the field of fire resistance of timber structures. Other than RISE ad Tallinn University, he has regular courses at Linneaus University and London City University. Dr Just is also a reviewer for several scientific journals, in the scientific board of the conferences Structures in Fire, Wood Building Forum, and Wood and Fire. Dr Just was a core group member of COST Action FP1404 “Fire safe use of bio-based building products” and is a head of Estonian delegation in CEN TC 250 SC 5. He is member of TC250 - SC5.T4 project team, drafting the next generation of EN 1995-1-2.
