Re: Unbalaced vertical force on SCBF

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There is also an example of this calc in the Steel Tips for BRBF's. It's in that steel tips to demonstrate one of the advantages of BRBF's over SCBF's is that the unbalanced check doesn't result in a big beam since the compression and tension capacities of BRB's are almost identical (compression is actually slightly higher).

Gerard, you say there is no zipper column required, per the design example in volume 3.  However, the beam must be large enough to resist the unbalanced loading condition in bending, Correct?
