D1.K.2.3 Design Parameters
The program contains a large number of parameter names which are required to perform design and code checks. These parameter names, with their default values, are listed in the following table.
The default parameter values have been selected such that they are frequently used numbers for conventional design. Depending on the particular design requirements for an analysis, some or all of these parameter values may have to be changed to exactly model the physical structure
Parameter Name  Default Value  Description 

CODE   
Must be specified as AISC N690 1984 to use the ANSI/AISC N6901984 code for checking purposes. 準拠する設計コード。「TR.48.1 パラメータの設定」を参照してください。
