Structural details
Eurocode 5 - Design of timber structures against fire actions

Appendices C (load-bearing function) and E (separating function) propose calculation methods for complete structures, walls and floors, including consideration of protective plates and their fastenings, and insulation filling cavities. These methods are subject to compliance with minimum constructive provisions.

• Dimensions and spacing

  Spacing between wall studs and floor joists must not exceed 625 mm.

  For walls, individual panels have a minimum thickness (in mm) of :

  $$t_{\text{p},\text{min}}=\text{max}\left[\frac{l_{\text{p}}}{70};8\right]$$
