Maximum load The tables give the max. permissible overloads in N/m2 corresponding to the clear spans between the supports and the radii of curvature calculated on the basis of experimental data, in order to ensure simultaneously a camber smaller than or equal to a two hundredth of the span and a safety factor equal to or greater than three with respect to breakage. The overloads given concern the panel with both steel claddings (ext. 0.6 mm - int. 0.4 mm). The values regarding the single span assume the existence of constraints at the two ends, such as to configure the static situation of the arc with thrust eliminated (hinges). The values concerning the multiple span assume the existence of hinges at the external supports and single supports to the internal ones. Thermal transmittance and unit panel weight
