Re: 97 UBC 1633.2.4 Deformation compatibilty - is that a typo?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Mark:

That is NOT a typo.  Instead, this sets a lower bound on the demand 
displacement.  In other words, no matter how stiff you think your 
lateral force resisting system is, you must consider an interstory 
drift of 0.25% for deformation compatibility.
