Hi, my friends.

On page 207 (see attached) Allan said unbalanced vertical force Qb is not required for one-story building or top story of buidings. But I do not see any section regarding this on AISC 341-05. And I remember this exception was being on AISC 341-02 or previous one if I am right.

This is critical issue for one story OCBF or SCBF because this unbalanced vertical force Qb makes huge steel beam size.

Please advise.

Thank you.

ohsung,

I would have to agree. This is currently not in the code for SCBF.

Don't worry about it too much. I have found a few more errors in the BRBF section of this book. :(
