Hello, I'm trying to model a tank with OOP settlement. The roof is fixed, with a beam structure that I find hard to model, as the roof plate is not welded to most beams, and the radial beams are free to slide over the circumferential beams, creating a lot of friction, and allowing some...
Thanks a lot pdiculous963... that makes sense. Specifically speaking, would you find a new gravity vector (for both hydrostatic pressure and body force) so that the lateral forces equal a given value? Would you use the Total Design Base Shear for this equivalence? Wouldn't it be possible to...
Thanks for your reply pdiculous963. I applied the loads as you describe, and in the absence of product in the tank, it's a critical loading condition.
In terms of seismic analysis, would you recommend applying the force and overturning moment from Annex E to a FEA model? If so, where would you...

A related question regarding wind pressure. When tanks are emmpty, they are liable to blow in. Sure. More so if the shells are not within tolerances. In API 579-1, the Plastic Collapse verification indicates that the wind load case pressure be applied * a factor, but I wonder...
