API 650 11th Edition Addendum 1

If you design a storage tank before, you are familiar with API 650 code. This code used for design of welded steel tanks for oil storage.

API 650 2007 Edition is valid now, but if you want to use this version, you must beware twice. Because, this edition has many misprints especially at Seismic Section. Also, with this edition the seismic section was completely changed. Before this edition, API used UBC 1997 code for seismic calculations. After this edition, API changed to ASCE 2005 for seismic and wind calculations.

API has not issued yet any addendum or errata for this edition.

But, they prepared a draft addendum document for 2007 Edition. If you want to use API 650 2007 Edition, you must read Addendum 1. Please note that, this addendum is in draft issue!
