D9.A.7 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 10A.1 contains a complete list of the available parameters and their default values. It is necessary to declare length and force units as centimeters and Kilograms before performing the concrete design.
Parameter Name | Default Value | Description |
---|---|---|
CODE | - |
Must be specified as JAPAN. Design code to follow. See TR.53.2 Concrete Design-Parameter Specification. |
BIAXIAL | 0.0 |
Value to define biaxial or uniaxial design type for Column
|
CLEAR |
3.0 cm (beam) 4.0 cm (Column) |
Clear cover for Beam or clear side cover for column. |
DEPTH | YD | Depth of concrete member. This value defaults to YD as provided under MEMBER PROPERTIES. |
EFACE | 0.0 | Face of support location at end of beam. (Note: Both SFACE & EFACE are input as positive numbers). |
FC | 210 Kg/cm2 | Compressive Strength of Concrete. |
FYMAIN | SR235 | Steel grade. Acceptable values for steel grade and their associated yield stress values are shown in the following table. Program automatically calculates yield stress value depending on design load type (permanent or temporary). |
FYSEC | SR235 | Same as FYMAIN except this is for secondary steel. |
LONG | 0.0 |
Value to define design load type
|
MAXMAIN | 41.0 cm | Maximum main reinforcement bar size |
MAXSEC | 41.0 cm | Maximum secondary reinforcement bar size. |
MINMAIN | 10 mm | Minimum main reinforcement bar size. |
MINSEC | 10 mm | Minimum secondary reinforcement bar size. |
MMAG | 1.0 | Design moment magnification factor |
NSECTION | 12 | Number of equally-spaced sections to be considered in finding critical moments for beam design. |
REINF | 0.0 | Tied Column. A value of 1.0 will mean spiral. |
SFACE | 0.0 | Face of support location at start of beam. |
SMAG | 1.0 | Design shear magnification factor |
TORSION | 0.0 |
Value to request for torsion design for beam
|
TRACK | 0.0 |
Specify the level of detail in the output:
|
WIDTH | ZD | Width of concrete member. This value defaults to ZD as provided under MEMBER PROPERTIES. |
