Building period when tanks protrude through roof
Building period when tanks protrude through roof
(OP)
Hello All! I am working on a building that is about 60 feet tall to the roof. However, supported on this roof level are a large number of 40' tall tanks. The tanks are very closely spaced, so it is almost like there is a solid 40' level above the actual building structure. Does anyone ever let storage or non-building components like this come into play when determining a building's period? If we were to set the "height" of the building to the middle of the tanks, then the reduced Cs formula is applicable. Thanks!

Often, rooftop equipment is quite rigid and effectively just adds to the mass of the roof diaphragm. Your stuff would seem to be of a drastically different scale however.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
