Q. Show the Vessel Supports?
Approved materials and allowable stresses, shall be used for vessels and their supports.
For structural shape support members in compression, where slenderness ratio is a controlling design consideration, no increase in the allowable compressive stress is permitted.
For supports outside the scope, for structural shapes, those in the AISC Manual of Steel Construction may be used.
The minimum design metal temperature for the vessel support assembly shall not be warmer than the lowest one-day mean atmospheric temperature at the installation site.
Localized shell stresses at all support-to-shell locations shall be evaluated, and shall include consideration as applicable of wind load, earthquake, and all other loadings.
Where reinforcing pads are used under supports, consideration should be given to stresses due to possible temperature differential between the vessel, pads and supports.
