Title: +038=221.001-#####T_01-Ruukki - Sandwichelement - Produktinfo.pdf
Following values have been used for calculating the above mentioned stud and fixing centers: • Maximum cladding system weight: - Mineral wool panels: 50 kg/m2 - PIR panels: 30 kg/m2 • Maximum stud centres: - Cladding system weight ≤ 30 kg/m2: c/c 1200 mm - Cladding system weight ≤ 50 kg/m2: c/c 600 mm • Stud fastener resistances: - Allowed tensile resistance: 0.3 kN/fastener - Allowed shear resistance: 0.3 kN/fastener • Minimum outer facing thicknesses in panels: - Mineral wool panels: 0.6 mm - PIR panels: 0.5 mm • Maximum wind loads (un-factored): - Mineralwool panelsWind pressure: 1.5 kN/m2 - Wind suction: 1.9 kN/m2PIR panels:Wind pressure: 1.5 kN/m2 - Wind suction: 1.7 kN/m2Load combinations: a) Wind loads (pressure and suction) b) Cladding weight c) Wind loads + cladding weight (interaction) • Safety factors: - Wind loads: 1.5 - Own weight: 1.35 - Material: 1.33Fastening base structure (Ruukki® energy panels) to load bearing frames
