Wind Loading Value For Roof Steel Structure of Storage

storage tanks top wind girder#0183;Wind buckling of the shell must be checked for all tanks,open-top and fixed-roof.When there is a cone roof,the top of the tank is braced so a top wind girder is not needed,but an intermediate wind girder may still be needed.Top and Intermediate wind girder can be apply to all type of tanksWind Girder vs Top StiffenerAPI 650 Tank - Intermediate Wind Girder designSee more resultsA rational design approach of intermediate wind girders on Jul 01,2015 storage tanks top wind girder#0183;In storage tanks,intermediate wind girders are used to prevent the buckling failure of tank wall caused by wind load.For the design of the intermediate wind girders,two key parameters must be determined the size of intermediate wind girders and the spacing between the girders.In the code API650,the spacing is expressed as the maximum height of the unstiffened tank wall and the size isWhat is a wind-girder? - AnswersOpen top or external floating roof tank do not have the benefit of this shell rigidity and therefore a circumferential wind girder is provided at or near the top of the shell to give it necessary
