Effective base plate area for a PFC section
Effective base plate area for a PFC section
(OP)
Morning guys,
I'm trying to calculate the effective area of a base plate for a PFC section (equal flange channel) sitting on a rectangular/square steel base plate but I'm not sure how to calculate the 'C' value.
I'm using British Standards: BS5950-1 clause 4.13.2.1
I have seen ways to work out the 'C' value with I and H sections but not sure PFC sections.
Any ideas?
Thanks!

Assuming only axial load in the PFC then,
effective area of base plate = compression load / (0.6*fcu), where fcu is strength of concrete below base plate.
effective area is approx. equal to length of PFC section (depth of PFC + 2*flange width) * (2c + t)
Rearrange to find C.
