D2.A.3 Design Parameters
The program contains a number of parameters which are needed to perform the design. Default parameter values have been selected such that they are frequently used numbers for conventional design requirements. These values may be changed to suit the particular design being performed. Table 1A.1 of this manual contains a complete list of the available parameters and their default values. It is necessary to declare length and force units as Millimeter and Newton before performing the concrete design.
|Parameter Name||Default Value||Description|
Must be specified as AUSTRALIAN to invokes design per AS 3600 - 2001.
