Integrated fire design = NFD (Natural Fire Design of Ruukki) Markku Heinisuo1), Jyri Outinen2), Mauri Laasonen1) 1) Tampere University of Technology, Finland 2) Ruukki Construction Oy, Finland Idea: Integrate following tasks: building information modeling, fire simulations, structural analysis ** More safe design: bulding and fire entities just for the project under consideration ** Enhance design: no manual data transfer between tasks, time&errors!

Integrated fire design NFD Case study 2: Ikea Tampere, Finland Description Storeys: Floor area: Steel structures

-1-2 (parts of the building) -35 000 m2 -Composite steel-concrete columns, Tubular steel trusses , WQ-welded profiles + hollow core slabs in 2-storey parts Wall cladding: -Sandwich panels (rock wool insulation) Roof structure: -Corrugated steel sheeting based solution Fire requirement: -R60 for load bearing structures Fire protection methods:- Prescriptive and performance based together -Automatic water extinquishers (water cooling the area + structures) -Intumescent coating Design and approvals The fire protection was approved by the building and fire authorities before the building process. Many negotiations were carried out in going into the details of the solution. In Finland the building authorities give the final installations of sprinklers and also fire protection materials are inspected afterward and documentation is put to the building manual for future inspections and maintenance.

Altogether the fire protection in this case was optimized to different areas using different materials and methods. The performance based design using simulation was used mainly by the 3rd party inspector to ensure that in certain spaces the calculated temperatures of the structures stays at safe 8 level.
