Fire research and regulatory material

1. Fire research and regulatory material European rules and standards Univ.-Prof. Dr.-Ing. Stefan Winter Technische Universität München Univ.-Prof. Dr.-Ing. Stefan Winter

2. Building regulations in Europe Europe is a mix of a big number of individual states – please don´t expect common rules! In addition some states are divided in provinces, e.g. UK in 4, GER in 16, which use partly own building regulations! Univ.-Prof. Dr.-Ing. Stefan Winter

3. Fire victims Univ.-Prof. Dr.-Ing. Stefan Winter

4. Building regulations in Europe And to carry it to extremes: If Special Buildings are designed, local authorities come to additional influence! Univ.-Prof. Dr.-Ing. Stefan Winter

5. General performance based fire safety requirements • Avoid start and spread of fire • Rescue people and animals • Protect the building strucuture and contents of the building • Allow fire fighting Univ.-Prof. Dr.-Ing. Stefan Winter

6. General performance based fire safety requirements In most of the European states prescriptive rules are given in laws and/or guidelines! If you stick to this general rules, you will fulfill the performance based requirement – but all other paths are possible as well! Univ.-Prof. Dr.-Ing. Stefan Winter

7. Summary of the possibilities to use timber structures and wood products in different building applications in responding countries if DC Univ.-Prof. Dr.-Ing. Stefan Winter

8. Possibilities to use timber structures and wood products in different building applications per country Univ.-Prof. Dr.-Ing. Stefan Winter

9.  22 m N 0,0 m MBO and M-HFHHolzR Non-loadbearing external walls in general: class A material and EI 0 or Class D material and EI 30 EI 30 Univ.-Prof. Dr.-Ing. Stefan Winter

10. Germany Building class 4 Necessary fire resistance: high fire retardant REI 60 and encasing class K 60 (see EN 13501-2 and prEN 14135) Univ.-Prof. Dr.-Ing. Stefan Winter

12. Germany „high fire retardant structures“ „...constructions, with combustible load-bearing and stiffening components with an encasing non-combustible fire protection cladding and non-combustible insulation material “ Univ.-Prof. Dr.-Ing. Stefan Winter

13. Germany Building Class 4 Target of encase criterion orinsulation criterion is to avoid ignition of the timber construction during a defined time period  T  300°C Univ.-Prof. Dr.-Ing. Stefan Winter

14. Germany Non-combustible material encases the complete timber structure Univ.-Prof. Dr.-Ing. Stefan Winter

15. Germany The encase criterion for a time period of t = 60 min leads to a fire resistance of REI 90 - REI 120 ! Univ.-Prof. Dr.-Ing. Stefan Winter

16. Variations for the encase criterion should be taken into account, e.g. for a time period of t = 30 min (K30) combined with a fire resistance of the construction element of REI 60!(especially in combination with sprinklers) Univ.-Prof. Dr.-Ing. Stefan Winter
