  • 5. How does Australia Compare with therest of WorldwideUnlimited storey height
  • 6. What limits timber construction in“dts” Building Regs – Fire• Type A & B dts requirements do notdirectly limit timber construction foro Beams,o Columns, ando Floors (other than lift pits)
  • 7. What limits timber construction in“dts” Building Regs – Fire• Type A & B dts requirements do limittimber construction by requiring– External walls, and non-load bearinginternal walls required to be fire resisting tobe non-combustible construction– Load bearing internal walls are to beconstructed from concrete or masonry
  • 8. What limits timber construction in“dts” Building Regs – Fire• Spec C1.1 Clause 2.2 Support for AnotherPart necessitates if the part it supports isrequired to be non-combustible, thenthat element is also required to be non-combustible• Therefore various walls supported byfloor, beams and columns must also benon-combustible
  • 9. Fire Resistance Level (FRL)Full size fire resistance testsORFire resistance by calculation
  • 10. Fire Resistance CriteriaStability Integrity InsulationPartition X XDoor X XLoad bearing wall X X XFloor – ceiling X X XBeam XColumn XFire resistant glazing X60 / 60 / 60- / 30 / -
  • 11. Fire Protection – Two Methods MethodWrapped in Plasterboard Exposed timber
  • 12. Calculations by AS 1720.4• Structural Only
  • 13. Calculations by AS 1720.4
  • 14. Integrity and Insulation• Shortly an EXPAN design guide willdevelopment a method for calculatingIntegrity and Insulation for floor and wallsystems• Basically it will say that 35 mm away from charlayer, timber’s temperature will be at roomtemperature
  • 15. Fire Protection• Fire protection provided by increasedthickness to timber elements
  • 16. Chat for FRL 90/90/90
  • 17. Fire Protection• Beam and columnselements needs increasedthickness for fire so anextra thickness is placed onexposed facesTimber fire protection
  • 18. Fire Protection• Shoulder to beam forms perfect corbel for floorcassette to sit on the beamTimber fire protection
  • 19. Construction FiresFirst Interstate Bank CA, USA
