Note (1) EBD-208.H22 is highty loaded support in Path 206 and EBD-214-E1-H6 is highly soaded support in Path 214.These are cantilevered supports.

Note (2) Seismic load is 1.0 times media-centered peak floor response spectra.

Note (3) Total loads = Dead Load + Operating Mechanical Load + Seismic Load V = Vertical Load H = Lateral Load Note (4) Anchorage capacities are based on bolt capacities shown in EPRI NP 5228 Rev.1 Table 2.12 and the safety factors from EPRI NP-6041-SL Rev.1 App. O.

Note (5) HCLPF = High Confidence of Low Probabilrty of Failure.

Note (6) Component Capacity is Equal to 5 x Catalog Lead Rating x 0.7 Note (7) Based on Pullout and Shear interaction.
