JSteph I got it. but I think i have to calculate the detail information of rafter, girder and column. many thanks again

Hi all, I am going to calculate the OVERTURNING STABILITY for a fixed rood storage tank (supported roof). In section 5.11.2 (API 650, edition 11), we see: MDL = moment about the shell-to-bottom joint from the weight of the shell and roof supported by the shell can anyone tell me how I assume...

ss pipe in not economical. we use a kind of tape.

Hi all friends I am calculating for the intermediate wind girder in a open-top storage tank. the tank needed one wind girder. Max. height of the unstiffened shell, H1=3.3 m Height of the transformed shell, Htr=6.2 m i would like to know, which place should be the girder installed on the...

Dear MJCronin yes, I am new designer in storage tanks field, for that reason I need to kindly help of you. Regards

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. regards

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...

Dear IFRs, you are right, and many thanks for the information, but owner wants using API 650 for designing the Tank. Can you help me more?
