RE: 2000 IBC

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The first eqn. (16-39) Should read as [Ta=(C)t * (h)n to power of ¾] where C
and h are identified following the eqn.. The second eqn. (16-40) should read
T= 0.1 N where N is the number of stories.

	Friends,

	I've been away for a while due to back surgery, but have re-joined
the
	list.  

	I am now working with a client who asked us to use the 2000 IBC, and
I
	have a question for those of you who are familiar with it.
Basically,
	the section on estimation of building period (1617.4.2.1) appears to
	have some equations misplaced or missing.  The first equation (Ta =
.1N)
	appears to belong lower on the page, where there is a missing
equation.
	I'm sure the first equation should be the typical period estimation
(Ta
	= Ct(hn)3/4).  Is there any errata for this code yet?

	Thanks,  Mike
