Wood Stress Increase for Wind

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I tried this message earlier but it didn't look like it went through.

I'm a little confused on what is permitted for the duration of load for
wind using the newer IBC and ASCE.  They both state that for allowable
stress design the allowable stress can't be increased for wind. 
Equations in Section 1605.3.2 can be used for alternate load cases where
the stress may be increased, provided the wind is increased by a factor
of 1.3.  Section 1605.3.1.1 states that for wood the duration of load
factors can be used for design provided it is designed in accordance with
Chapter 23 - wood chapter.  I looked through chapter 23 for some general
information regarding the duration of load with the load combinations and
didn't find anything.

Can the 1.6 duration of load factor be used for wind design with wood? 
If so, does the wind value have to be increased by 1.3?  Also, if the
design is based on components and cladding, does the wind value need to
be increased for this as well?  The IBC tends to indicate the increase is
only needed for MWFRS if it is done by the simplified method.  Components
and cladding design is not limited to simplified building analysis.

One reason I ask is to know what Simpson Anchor design values I can use. 

I can't wait until all the design specifications catch up to one another.
