Wind Force Coefficients
Wind Force Coefficients
(OP)
I am sure this has been asked but I can't seem to find it anywhere. Does anyone know where I can get a book that discusses the wind load provisions of the ASCE 7? I have the guide to the wind load provisions and this is fine but I want something more elaborate. I really need something that discusses force coefficients (shape factors) for different non-building structures that can be used with the ASCE 7 design procedures. I looked on ASCE website but to be honest I just hate trying to find things on that site and I don't have much luck.
Thanks
Thanks

It literally tears apart piece by piece the new ASCE7-05 almost to an embarrasing point. Good Luck.

This is a very nice book "Guide to the Use of the Wind Load Provisions of ASCE 7" by Kishor C. Mehta and James M. Delahay

The Structural Engineers Association of Washington has a three volume set of books that are published by Applied Technology Council (www.ATCouncil.org), The first two volumes, SEAW/ATC 60 are the commentary on the wind load provisions (of ASCE-7, IBC and IRC) and example problems. SEAW RSM-03 is a Handbook of a Rapid-Solutions Methodology for Wind Design (also with numerous example problems). All three volumes cover the subject in more detail than one should ever want to see.
Even though the 3 books cover the subject of wind loads in excruciating detail it seems like a major waste of time (and money since the 3 volumes cost about $160)for engineers that have to comply with the 2003 IBC to wade through all of this detail just to develop the wind loads on a structure.

The moment you introduce the word "shielding" ASCE requires either a wind load test or approved research on your issue.
Their are no other proven ways to cut corners as it relates to wind loads.

I think the shielding statements refer to shielding from other structures and terrain, not from parallel identical frames. The force coefficients in figure 6-22 account for the shielding on the leeward frame due to the windward frame. This is why you get Cf factors of 2 - 4. The Cf factors in figure 6-21 do not account for this and you get Cf = 1.6 - 2.0.
I read through the comentary last night and it made reference to a book put out by ASCE called "Wind Forces on Structures" for additional force coefficients. I am going to try and get that book. Thanks to everyone for their input.
