Loads
The following loads should be taken into account:
•
Platform self-weight (PSW
M
and PSW
CR
):
-
Main Platform self-weight (PSW
M
)
-
Cone Recovery Platform self-weight (PSW
CR
)
•
Formwork self
–
weight (FSW):
-
ENKOFORM V-100: 0.6 KN/m
2
-
ORMA: 0.8 KN/m
2
•
Live load (LL
M
and LL
CR
):
-
Main platform (LL
M
): 1.5 KN/m
2
-
Cone recovery platform (LL
CR
): 0.75 KN/m
2
All these loads are distributed along the Main Beam:

a = influence width
l = hollow length
h = formwork height
The distributed load (q) calculated in this formula, is the load applied in the main beams
1 and 4.
It must be verified that these beams are the most loaded, if not, the calculations must
be done on the most loaded beam.

In this section a simplified way to calculate and verify KSP Platforms is shown. Is responsibility
of each engineer to check that all the simplification hypotheses made in this example (see 5.3.2
“Clarifications…”), are applicable to its particular case.
