Which standard should be referred to for multi-legged horizontal containers?
Thread Content
Dear seniors, the horizontal container as shown in the figure below has the following parameters: 1) It has 12–20 legs； 2) Diameter 8m, length 20m, filled with municipal sewage, at near atmospheric pressure. 3) It is fabricated on-site using the assembly welding method. 4) There are only a few external heat exchange fins in place; their number is minimal, so they do not affect the proper design of the legs. Question: Which national standard should be referred to for design?
This falls under non-standard branch withdrawal; there are no standards to refer to, so it must be designed and calculated manually
It’s actually a saddle support; the middle part isn’t built all the way through. The key to calculating multiple saddle supports lies in determining the reaction forces at the supports and the distribution of moments. This can be calculated using the methods outlined in statics manuals. In terms of software, finite element analysis along with SW6-2011 4.0 can be used for such calculations. However, the stability of those leg-like components requires special consideration, and finite element analysis is the best approach. I’m not sure what the purpose of not building the middle part all the way through is; if simplicity is desired, it can be built all the way through, allowing the use of standard saddle support design formulas
