Technical Reference 5.47.1 Parameter Specifications Purpose This set of commands may be used to specify the parameters required for steel and aluminum design.

Please see section 5.16 for the definition of member group names. Deck names are explained in section 5.20.7. Description Parameter-name refers to the "PARAMETER NAME" (s) listed in the parameter table contained in the Steel and Aluminum Design section.

f1 = Value of the parameter.

The details of the parameters available for specific codes may be found in the following places: American AISC ASD & AISC LRFD - Section 2 of this manual AASHTO - Section 2 of this manual AISI (American Cold formed steel code) - Section 2 of this manual All other countries - International Codes Manual American Aluminum specifications - International Codes Manual ASCE72 Transmission Tower code - International Codes Manual

API code - International Codes Manual The user can control the design through specification of proper parameter. The PROFILE parameter is available for only a limited number of codes like the AISC ASD and AISC LRFD. The user can specify up to three profiles (a1, a2 and a3). Profile is the first three letters of a section name from its steel table, like, W8X, W12, C10, L20 etc. The PROFILE parameter-name is used only for member selection where members are selected from each of those profile names. The PROFILE for a T-section is the corresponding W-shape. Also, the shape specified under PROFILE has to be the same as that specified initially under MEMBER PROPERTIES. CODE parameter lets you choose the type of steel or aluminum code to be checked for design. The default steel code depends on the country of distribution. Example

PARAMETERS CODE AISC KY 1.5 MEMB 3 7 TO 11 NSF 0.75 ALL PROFILE W12 W14 MEMB 1 2 23 RATIO 0.9 ALL

Notes 1) All unit sensitive values should be in the current unit system. 2) For default values of the parameters, refer to the appropriate parameter table.
