PERMIT STATUS (no response required) 3/6/2012: Review completed. Comments issued.

Advisory Comment (no response required):  This review is based on the requirements of the Anchorage Administrative Code (AAC), 2009 International Building Code (IBC), 2009 International Residential Code (IRC) and all adopted references thereto as amended by MOA. The following comments must be addressed before a permit can be issued. The approval of plans and specifications does not permit the violation of the codes, or any federal, state or local regulations.

1) Reference pages 1 and 2 of the calculations. Please clarify how the loads for this anchor were determined. Per page 1 the lateral load is 397.45 lbs. Per the drawings it appears that only one cable is being used to resist this load (in the condition where the cable are installed orthogonal). This would make the tension in the cable 397.45/cos(60) = 794.9 lbs, and the tension 794.9*sin(60) = 688 lbs. It seems the anchor should be loaded with 688 lbs of tension and 397 lbs of shear. Please note that it's possible that the drawings do not represent the intent and it was meant to have the orthogonal cables on all four corners. Please also note that based on the geometry if there are only orthogonal cables on two corners it is possible the load due to the unit trying to twist could be higher than the lateral load. This would need to be verified as well.
