Table values mean the following:
perm. main girder spacing b [m]
actual prop load [kN]
– The deflection has been limited to
l/500
– Secondary girder assumed as single
span
For cantilevers:
c < 75 cm; e = c/2
c ≥ 75 cm; e = 50 cm
c: width of main beam interior span or
prop spacing
e: length of cantilever
