  5. 5. How does Australia Compare with therest of WorldwideUnlimited storey height
  6. 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. 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. 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

  14. 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. 15. Fire Protection• Fire protection provided by increasedthickness to timber elements
