Executive Summary ver 4.00
Introduction:

Page 4 of 75

This spherical vessel is designed for use under ASME VIII-1 service. The sphere and its supports are subject to IBC 2009 seismic and wind loads. The support structure is analyzed by Finite Element Analysis. The rules of VIII-2 are used with VIII-1 allowed stresses todetermine the acceptability of the sphere and support structure under all load conditions. Summary Conclusions: Materials Vessel material strength properties used in this report are obtained from ASME IID, Table 1A, and are suitable for VIII-1 components. The rules of ASME VIII-2 are used to set the stress limits of the vessel materials. Material properties are shown for SA-299 A and SA-516 70....
