Re: Minimum Flexural Strength of Columns

[Subject Prev][Subject Next][Thread Prev][Thread Next]
This makes sense only refering to the moment resisting frames, this provision ensures that the beam yields before the column does, and therefore prevents a weak floor failure during a seismics event. On Wed, 30 January 2002, "Alex C. Nacionales" wrote
    The UBC code states that the flexural strength of columns framing into a joint
must at least be 1.2 times flexural strength of beams framing into that joint.
 
Does this provision apply to only to Special Moment Resisting Space Frames(SMRSF)? Can this provision be disregarded fo frames assumed to support gravity loads only like in shear wall systems or dual systems?
 
Thanks in advance.
