I used a Cf of 1.0. I looked at figure 6-19 for a round tank, very rough you have 0.8, 1.0 and 1.2 so I use a 1.0 as being conservative for the sphere (probably too much). But even with this very conservative value the overall loads ended up being very similar (within 10%)
Thansk for the info. What I was trying to do was run the original loads as the structure was designed. Then we reran it under the new loading conditions. They wanted to make sure it was designed right originally and how it would fair under todays loading conditions. When all is said and done...
I'm trying to compare the current wind loads to the design wind loads for some methane gas spheres. They were designed in 1978 so I'm assuming that the Building Code would have referenced the then-current standard, ANSI A58.1-72. If someone has a copy I'd like to get some information from it...
