Table values mean the following:
perm. main girder spacing b [m]
actual prop load [kN]
– The deflection has been limited to l/500
– Main girder support at centre of girder nodes
– Secondary girder assumed as single span
– For prop loads < 28.0 kN, 1 x GT 24 as main
beam is sufficient.
Cantilever e [m]
For cantilevers:
c < 90 cm; e = 30 cm
c ≥ 90 cm; e = 45 cm
c: width of main beam interior span or
prop spacing
e: length of cantilever
