Important results from the project
FIRENWOOD was a project for developing fire design models of engineered wood structures and for developing assessment method for bond line integrity in fire. Fire design methods for engineered wood structures (I-joists, CLT, glulam, glued-in rods) have been improved and verified. Test methods for assessment of adhesives with regard to elevated temperatures and fire have been developed with 11 different adhesives and softwood. The outcome of FIRENWOOD is presented and discussed at standardization committees CEN TC193 SC1 and CEN TC250 SC5.
Expected long term effects
Results and expected effects of FIRENWOOD have been 1) the common understanding and agreement of behaviour of bond lines of engineered wood in fire; 2) improved fire design models for engineered wood (I-joists, glued laminated timber, cross laminated timber, glued-in rods) taking the adhesive behaviour into account; 3) simple assessment methods for adhesives according to their fire behaviour.
Approach and implementation
The project was based on special high competencies of the partners. Project was divided into work packages. Monthly update meetings were organized to discuss the findings and plan the next steps. The project finished with common agreement on design models and assessment methods. The results were presented and discussed with the adhesive producers and proposed for implementation to standards. The results will be published as Firenwood reports and in the scientific publications.
