*) The values should be reduced by 20% if the longitudinal joints of the panels are executed by means of finger joints.     The present values are only applicable for K1multiplan panels. Data source: Permit Z-9.1-242, IfBt.     The values for loads below an angle of 0 ÷ 90 ° shall be taken from the permit.     Straight line interpolation may be carried out between the nominal values specified.
