Shear Load Transference - Shear load is transferred by 
rivets into the floor / ground surface or the perpendicular 
walls, ceiling & roof at a rate of 1.21 kN per 4.0 mm diameter 
rivet.
Fixing rivets at 200mm centres complies with the 20-minute 
flame barrier requirements and delivers 14.5 kN of shear 
capacity transfer per panel (6 on each side) horizontally, 
and 12.1 kN per metre in vertical joints. Limited by the 
ability of the panel to transfer the shear.
* Figures for 1.2m & 4.8m high panels are extrapolated.  It is  
  acceptable to extrapolate Bracing Capacity heights between  
  1.2m & 4.8m.  For heights outside of this dimension range,  
   Diaphragm Analysis is required to establish Bracing Capacity.

The above table lists ultimate wind load pressures for strength design and the pressure corresponding to a Span/150 single span deflection for 
0.6mm G300 steel skins bonded to a EPS-FR polyisocyanurate core and in accordance with Serviceability Limit State criteria as per AS1170.0 
- Table C1. The designer shall determine if Span/150 deflection ratio is appropriate for intended use. Loads for a more stringent deflection ratio 
can be determined by linearly proportioning the loads provided. Differential thermal effects are not incorporated in the loads provided.
