Example Calculation 1no. Noggin minimum 38×63mm fixed with 2no.UZ–clips (1 each end) Instantaneous design value (Wind kmod 1.1) for noggin (centre or end) = 1.269kN Instantaneous design value (Wind kmod 1.1) for Screw fixing PSTS8x85mm (assume panel has 38mm bottom member = 1.684kN Buttress wall with 4 noggins maximum loading 1.269* × 4 = 5.076kN
1no. Noggin minimum 38×120mm fixed with 4no.UZ–clips (2 each end) Instantaneous design value (Wind kmod 1.1) for noggin (centre or end) = 2.115kN Instantaneous design value (Wind kmod 1.1) for Screw fixing PSTS8x85mm (assume panel has 38mm bottom member = 1.684kN Buttress wall with 4 noggins maximum loading 1.684* × 4 = 6.736kN
