Source for Examples of Seismic Anchorage Details Detailed illustrations of examples of seismic anchorage details were developed by Working Group #9 of the Japan 300 mm (“J300”) effort, and were printed in their Report No. 9 in the 2nd Lecture, ICs Factory Design for 300 mm Wafer Line Standardizing Study, December, 1996.
Design Example (refer to Figure R4-1 for illustration of example) Disclaimer: the calculations below are not a complete seismic analysis. A complete analysis might also include such things as: stress distribution through a multiple-fastener connection; prying action; bearing stress; simultaneous combined stresses on the fasteners; and a review of weld geometry. A complete seismic analysis should be done by a qualified engineer. Design Example (refer to Figure R4-1 for illustration of example)
