Shell Buckling Evaluation of Thin-Walled Steel Tanks

The American Standard API 650 (2007) attributes buckling of the shell to wind action.For this reason,the standard proposes the attachment of stiffening rings (wind girders) around the shell of the tank.The use of a wind girder at or close to the top of the shell is mandatory for open-top tanks.The required section modulus Z top (expressed in cmSecton Moduli of Stiffening Rings per API 650Mar 17,2006 API 650 tanks Shell Stiffening Rings#0183;Secton Moduli of Stiffening Rings per API 650.Friday,March 17,2006 By Novice . any suggestions on how to proceed in cases of pitting in the weld located between the floor and the shell of the tank critical oneImages of Api 650 Tanks shell stiffening rings imagesstiffening rings for API 650 Tanks - API (American Jul 06,2007 API 650 tanks Shell Stiffening Rings#0183;Secondary stiffening rings acc.API 650 Assume that based on D,course heights ,thickness,wind speed,..on calculates 1/ height of transformed shell= H_transf 2/ H_unstiffened =the height of the Unstiffened shell lets note n API 650 tanks Shell Stiffening Ringslt; (H_trans H_usntiffened ) API 650 tanks Shell Stiffening Ringslt; (n+1) n= could be equal to 1 or 2 or 3 etc.If n =0 then no secondary ring is neede.

The proposed construction is similar to the API Std.650,but the foundation ring is moved in the outside direction where it can not be influenced of the load of the shell and the tank roof upon it.When there is soil settlement under the tank,the reinforced concrete ring does not allow full drain of the water so that this solution is unfortunate.Foundations of aboveground steel tanksThe proposed construction is similar to the API Std.650,but the foundation ring is moved in the outside direction where it can not be influenced of the load of the shell and the tank roof upon it.When there is soil settlement under the tank,the reinforced concrete ring does not allow full drain of the water so that this solution is unfortunate.Date November 2009 - American Petroleum InstituteThis package contains Addendum 2 of API 650,Welded Tanks for Oil Storage,11th Edition.This package consists of the pages that have changed since the June 2007 printing of the 11th edition and Addendum 1 dated November 2008.To update your copy of API 650,replace,delete,or add the following pages as indicated.
