2. Allowable loads are based on National Design Specifications (NDS) for wood construction, 2005 Edition.
3. Design loads are based on Southern Yellow Pine wood species with a specific gravity of 0.55. Allowable loads for other species or conditions must be adjusted according to NDS 2005.
4. Nails are common wire nails as defined in NDS 2005. Lag screws are as defined in section 11.1.3 of NDS 2005. Welded connectors steel is ASTM A36(Fy=36 ksi). Bolts shall be per section 11.1.2 of NDS 2005.
5. Allowable gravity loads have been adjusted by load duration factors of 100%, 115% and 125% for live, snow and construction loads respectively.
6. This catalog reflects design changes and design adjustments to some Nu-Vue products. The tables and notes in this catalog supercedes all previous documents. Nu-Vue reserves the right to change specifications design without notice and liability for such changes.
7. The structural products listed in this catalog have been evaluated per evaluation from Miami Dade County, Florida and Florida Department of Community Affairs.
8. Design loads do not include 33% increase for steel and concrete.
9. Allowable uplift loads have been adjusted by a load duration factor cd of 1.6 (160%) applicable to wind and earthquake loads per NDS 2005.
10. Design conforms to 2006|2007 Edition of Florida Building Code and latest changes.
11. Combined load of Uplift, L1 and L2 must satisfy the following equation:
| |
Actual Uplift

12. All tests have been conducted in accordance with ASTM D-1761.
13. Tables based on Miami-Dade Notice of Acceptance need not be signed and sealed by a P.E.. Other tables need to be signed by a P.E.
14. All welded Hangers and Connectors designed to resist Uplift and Lateral Loads, are manufactured under a quality assurance program by Nu-Vue or under contract by an independent manufacturer. All welded products are signed & sealed by a Florida P.E.
15. The design loads listed are based on the least value of the following:
1) The lowest ultimate load divided by three.
2) The lowest load producing 1/8" deflection.
3) Calculations based on 2005 NDS, AISC steel manual and other applicable codes.
16. Concrete in tie beams and grout and mortar in concrete masonry shall be 2500 psi. Concrete masonry shall comply with ASTMC90.
