unsupported span

[Hisham]

Hi all

I have a simle question

in longitudinal systems what is meant by unsupported span for the deck center girder CG ?
is it the spacing between (transverse Web Frames) or the distance between the two BKHD (Bulkheads) that are carrying the CG ?

i am using GL

is it the same in BV?

hope to find the answer here?

thanks all

Between bulkheads. The web frames are supported by, but do not support, the girder. They (the web frames) also have unsupported spans of their own.
Those letter designations are not common building terms.
Are you reading a plan? CG, for example, is empirically understood to mean Center of Gravity. Your're using terms that have different or no meaning outside of your particular circumstances/plans.

Hi Alan,

I assume this only counts for the deck center girder and not for the other longitudinals (stringers) as those are supported by the transverse webframes.
Or am I mistaken here?
