problem in the disigning a potable water tank 2

[69020211]

Hi

I can disign a potable water tank with D=10 m and H=10 m and with rafter supported fixed cone roof (no girder and no column) and roof slope is 1:16. I want calculate the number and type of rafters that don't fail. Can you help me how do I calculate them? Can you introduce me any book for this problem?

Thanks

- API 650 will give you guidlines on rafter spacing.
- AISC will give you info on rafter design.
- The Strucutural Engineering Handbook has a method for designing the compression ring for roofs without center columns.

yosamitysamm ,

The API 650 doesn't give more detail about rafter design.
Can you tell me which part of AISC gives information about rafters?
and I don't have The Strucutural Engineering Handbook, please give me the address of the Handbook that get it.

I assume you have read IFR's reply in thread 1452-257294 and since you have decided against a center column, dome or umbrella, I suggest you enlist the help of a structural or civil engineer familiar with the AISC ASD Steel Manual. It is not a difficult solution but in your case could involve more decisions than you mention. Good luck.

Let me guess.....

Is this the first time you have designed structural steel for a storage tank ?
