AISI COLD-FORMED STEEL DESIGN MANUAL, CHANGES IN ALLOWABLE LOAD CALCULATIONS
The beam and column loads given in this catalog are based on the 1996 edition of the AISI Cold-Formed Steel Design Manual. Since the issuance of the first Nuclear Power Engineering Catalog (NE-1), the AISI Engineering Committee had continued to alter and modify the formulae for calculating allowable loads. Therefore, loads in the catalog may be different from those in the NE-1. Unistrut’s products for the nuclear industry have not decreased in strength. The materials and processes used to manufacture Unistrut nuclear products remain the same as they were for NE-1. However, the AISI formulae for allowable loads has changed. As a leader in the nuclear industry for strut products, we believe that adhering to the latest engineering design standards for cold-formed steel is imperative. This catalog represents those latest design standards.
ASTM A 1011 STANDARD VS. ASTM A 570 STANDARD
In 2000, ASTM discontinued specification ASTM A 570 and replaced it with ASTM A 1011. Unistrut completed an engineering review of the two specifications and concluded that the chemical and mechanical properties of A 1011 SS Grade 33 are the same as A 570 Grade 33. Unistrut reserves the right to certify parts made from ASTM A 570 Grade 33 to ASTM A 1011 SS Grade 33.
