Minimum Design Loads for Buildings and Other Structures, ASCE 7-10 ASCE/SEI American Society of Civil Engineers May, 2010 English 658 p pdf 21.8 MB ISBN: 9780784410851 Minimum Design Loads for Buildings and Other Structures, ASCE/SEI 7-10, is a complete revision of ASCE Standard 7-05. ASCE 7-10 offers a complete update and reorganization of the wind load provisions, expanding them from one chapter into six to make them more understandable and easier to follow. ASCE 7-10 provides new ultimate event wind maps with corresponding reductions in load factors, so that the loads are not affected. It updates the seismic loads of ASCE 7-05, offering new risk-targeted seismic maps. The snow load, live load, and atmospheric icing provisions of ASCE 7-05 are all updated as well.

This standard was developed by a consensus standards development process which has been accredited by the American National Standards Institute (ANSI). Accreditation by ANSI, a voluntary accreditation body representing public and private sector standards development organizations in the U.S. and abroad, signifi es that the standards development process used by ASCE has met the ANSI requirements for openness, balance, consensus, and due process.

The material presented in this standard has been prepared in accordance with recognized engineering principles. This standard should not be used without first securing competent advice with respect to its suitability for any given application.

In the margin of Chapters 1 through 23, a bar has been placed to indicate a substantial technical revision in the standard from the 2005 edition. Because of the reorganization of the wind provisions, these bars are not used in Chapters 26 through 31. Likewise, bars are not used to indicate changes in any parts of the Commentary.

I've been tasked with designing a foundation system for a 60' tall, 50,000 gallon ground-support tank used for liquid storage. My firm has had a older 'rule of thumb' reference on tank seismic design from IBC 2000.
However, looking through ASCE 7-10's seismic requirements, it would seem section 15.7.6 would be the appropriate method to use in finding the seismic base shear for the tank. I've yet to find a good design example for ASCE 7-10 Ch. 15, if anyone could point me to one? But I have specific questions as well:
1. How is W_c (portion of liquid weight sloshing) calculated? Is this provided from the tank manufacturer typically? Further, are there any approximate methods out there?
2. Is T_L the same as it would be for typical buildings? (i.e. using Figure 22-12)
3. At what elevations are the impulsive and convective base shears applied? I imagine the convective effects would occur at a higher elevation than the typical impulsive effects?
I would appreciate input on any of these questions. Thanks!
