I remember two instances where a non bearing type splice is adopted.

1) When the engineer wants to avoid milling of column ends due to
non-availability of adequate fabrication facility or from cost
consideration. Milling seems to be expensive.

2) When uplift and moment in column result in a flange force (tension)
which is comparable to compression in column flange due to downward load
and moment in other load combination. In this case the splice plate and
bolts are to carry all the flange forces. Hence, milling of column ends
are not necessary and a gap may be provided.

Dear members,

First of all thanks to all the members for sharing their technical
issues
even though there are silent observers like me.

I have one query regarding bearing and non bearing column splice
connections.
In column splice bearing connection, Ends are prepared for contact in
bearing, hence loads
are primarily transferred from upper column to lower column through
ends of
contact and only some
of the loads through cover plates.
But in Non bearing connection(There will be a gap between upper and
lower
column),
Loads are primarily transferred through Flange and web cover plates.
My doubt is where exactly the non bearing connection will come into
the
picture
from practical point of view?
Why should we provide gap between members with respect to practical
application?

Can anybody please elucidate on this?

Regards,
C.Sajeesh
