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...
My question is in regards to AISC 358-05 prequalified Bolted Unstiffened and Stiffened Extended End-Plate Moment Connections.
Fig. 6.1 of that specification shows the Extended end-plate configurations as a beam framing into the flange of a continuous column.
Does the prequalification apply...
I'm hoping that someone can provide me with a link to a website that sells or advertises a computer program called SVAP. I don't know anything more about it other than that it is used for foundation analysis and takes into acount high vibrations from equipment. Thanks in advance.
Say I have two equations. One equation is used if x > y. The other is used if x <= y. If for some situation x > y, I only want the function associated with that condition to show up on my printout. I know I can simply drag the equation I want onto the printed portion and take out the...
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...
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...
