    Spherical Vessel Seismic Loads

    I'm looking for guidance on the proper determination of seismic loads on a spherical vessel. Specifically, I need the loads to size the foundation and anchor bolts. I have experience with design of Above Ground Storage Tank foundations and am looking for an analog to API 650 Appendix E which...

    The problem I'm facing is in regard to equation E.6.1.2.2-1 which gives the height from the bottom of the tank shell to the center of action of the lateral seismic force related to the impulsive liquid force for the slab (pile cap) moment, Xis. When I calculate this distance, I get a value that...

    Seismic Design of Storage Tanks: EQ E.4.5.1-1b

    I'm looking at the 11th ed. of API Std.650. I'm confused by the equation for Impuslive Natural Period (E.4.5.1-1b) given as: Ti = 1/27.8 * CiH/sqrt(tu/D) * sqrt(E) Units (by definition in Sec E.2.2): My values: Ti: sec 1.23x10^6 s Ci...
