Hi everyone!
I have a problem to with Etab section classification,
I use
code: BS5950-2000
steel section: Chanel (widthxdeptxthick)(50x100x3mm)
Yeild strength: fy= 290MPa

According to BS5950 table-11
d/t<40*(270/fy)^0.5
d/t = 31.33
40*(270/fy)^0.5 = 38.95
so it is ok
But in Etab if we model the section as above it said section classification 4.

Any one have any idea on this?
thanks
