RE: 2013 Codes

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It's actually (IMO and that of many others) more complicated. I'm not sure 
why they chose to do it as they did, but they decided to remove the 
"Importance Factor" and instead provide THREE wind speed maps.

The wind speeds are "higher," but so as to induce forces at the "factored" 
level such that they've reduced the load factors in those combinations that 
 include wind.

Puff, puff.

And other stuff...

And spread things out over several chapters...


Well, the point is, it may be BETTER but it's not what I think ANYONE would 
 call "simpler."

I just started looking at the wind chapter. There are changes. Not sure if 
it is any simpler. On Nov 6, 2013 1:33 PM, <lrhauer(--nospam--at)> wrote:
