Re: UBC 1633 - Detailed Systems Design Requirements

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You are correct, the provisions do not apply to seismic zone 1.  There are
however material specific requirements for seismic zone 1 (such as masonry)
that set minimum levels with the same basic intent as section 1633.

Reality is the anticipated force levels and displacements in seismic zone 1
are minimal and should be far less than the typical wind force requirements,
except for unusually heavy structures.
