I have a tank farm with deluge sprinkler protection on the vessels, steel pipe rack and supporting steel. The debate that has arisen is whether this type of arrangement really needs to be seismically braced. The issue is that it is not a structure, and not occupied. However the materials within the tanks are flammable/combustible.
Now to what degree of seismic resistance the structural steel and tank supports are designed to is unknown. Is there an exemption for this type of installation? Based on the information provided by structural, the occupied buildings would be braced, no question there. But for exterior vessels, that is the question. Soil Site Class = D Occ. Class. = I Seis. Des. Cat. = D Structure Ip = 1.0 but might be argued to be 1.25 (Occ. Class II) Craig L.
