Installation of bottom stiffening plates in large storage tanks
Thread Content
Products designed in accordance with GB50341-2014 _ Code for Design of Vertical Cylindrical Welded Steel Oil Tanks (atmospheric pressure vessels) have varying numbers of stiffening plates on their bottom plates; some have none at all. Which approach is more reasonable?
Simple: Reinforcement plates are generally provided when there are foundation bolts; they are usually not provided in the absence of foundation bolts.
What is mentioned are large storage tanks, and foundation bolts have not been taken into account.
Find a specification or example and look at the calculation sections for towers or vertical vessels, as well as the skirt foundation ring. Anchors resist the bending moments caused by wind or earthquakes; you understand this ； σbmax represents the compressive stress of the foundation concrete; by treating the foundation ring plate as a rectangular cantilever plate and using reinforcement plates to divide it into smaller sections, the bending moment is reduced, allowing the plate thickness to be decreased ； The rib plates share the pressure transmitted from the foundation ring plate; they are considered as compressed members, as specified in the codes. The larger the quantity, the thinner the rib plates can be. For pipe supports and hangers, as to how thick the base plate of the column should be, why reinforcement is needed for the base plate, how much reinforcement should be used, and what thickness the reinforcement plates should have – it’s the same principle applied here.
The lifting force of large storage tanks or dizhen loads may affect the foot bolts
