No Are anchors required limit maximum number of blocks per bay? Yes Are anchors required to resist Seismic displacement? Yes Remove blocks at anchored bays?Yes Allowable PV Dead Load = 5 psf Maximum Number of blocks per bay = 5 Blocks Attachment Capacity (uplift) = 505 lbs Attachment Capacity (lateral) = 820 lbs See attached calc for anchor capacity Positive Attachment Requirements: Note: "North" always refers to panel north, which is the raised edge of the panel. Note: Residual forces shown on Attachment calculations are ASD-level forces with load combinations applied. Pressures shown do not include load combinations.
