Re: H/b ratio for Low shear walls

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dennis:

Two sections of the UBC may do what you want here.  Section 1629.10.1 
says "Alternative lateral-force procedures using rational analyses 
based on well-established principles of mechanics may be used in lieu 
of those prescribed in these provisions."  Section 1632.5 provides a 
similar allowance.  These sections are provided to allow designs that 
aren't strictly code-compliant when sufficient engineering is 
provided.

The key words in your question are "when supported by analysis."
