Notes:
. Values have been calculated using the allowable “Stress Design” method, taking self weight, imposed loads (wind load) and temperature (Δt=±20ºC) into account.
. If loads are effected as downwards l/200 and l/150 , ıf loads are effected as suction l/150 deflection limits have been used
. Values have been calculated using the steel quality fγ=240 Mpa(Yield Strength).
. In Panel weight calculations, Polyurethane density is taken as 40 kg/m3 and Polyisocyanurate density is taken as 42 kg/m3.
