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.
