Buckling due to Wind in Corroded Condition

For API 650 tanks the wind calculations (both resistance to overturning and for buckling) are performed in the new condition unless the customer specifies otherwise. As such we have always had a checkbox in the "Wind" portion of our design screen to specify that the wind calculations are to be done in the corroded condition. We have now added a second checkbox to allow you to do the resistance to overturning in the "new" conditiong but do the shell buckling analysis in the "corroded" conditiong. If this checkbox is marked, then the check for wind girders will be evaluated in the corroded condition rather than the new condition.

We continually make additions and modifications to our ITSdesign software to meet the needs of our clients. We have several modifications being evaluated or worked on because of requests received. A trial version of ITSdesign is available for download at www.innovativetanksolution.com.
