Wind suction load (pull-through strength): According to TrayPan, the needed amount of screws in corner area is 3no per panel end. In mid areas 2no per panel end is enough. Manual calculation: (wind suction load x panel module width x span/2) /allowed tensile strength of fastener. • Mid area: (-0.6 kN/m2 x 1.2 m x 6 m / 2 ) / 1,25 = 2no → 2 fasteners / panel end • Corner area: (-0.9 kN/m2 x 1.2 m x 6 m / 2) / 1,25 = 3no → 3 fasteners / panel endSelf weight (shear strength): The needed amount of screws is calculated manually based on system weight: • Base structure weight: The weight of ‘SPA230E ENERGY’ is 30.4kg/m2 (www.ruukki.com/energypanels) • Cladding + support stud weight: 20kg/m2 • Total wall weight: 50.4kg/m214 EN Ruukki Forma design instructions
