D4.A.4 Design Parameters
The program contains a number of parameters which are needed to perform design per CSA Standard A23.3-94. These parameters not only act as a method to input required data for code calculations but give the engineer control over the actual design process.
Default values, which are commonly used numbers in conventional design practice, have been used for simplicity. The following table contains a list of 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|
|CLB||40||Clear cover to reinforcing bar at bottom of cross section, in mm.|
|CLS||40||Clear cover to reinforcing bar along the side of the cross section, in mm.|
|CLT||40||Clear cover to reinforcing bar at top of cross section, in mm.|
|DEPTH||YD||Depth of the concrete member. This value defaults to YD as provided in the MEMBER PROPERTIES.|
|EFACE||0.0 (Face of Support)||
Distance of face of support from end node of beam. Used for shear and torsion calculation.
|FC||30||Specified compressive strength of concrete, in N/mm2.|
|FYMAIN||400||Yield Stress for main reinforcing steel, in N/mm2.|
|FYSEC||400||Yield Stress for secondary reinforcing steel, in N/mm2.|
|MAXMAIN||7 (Number 55 bar)||Maximum main reinforcement bar size.|
|MINMAIN||0 (Number 10 bar )||Minimum main reinforcement bar size.|
|MINSEC||0 (Number 10 bar)||Minimum secondary (stirrup) reinforcement bar size.|
|MMAG||1.0||A factor by which the column design moments will be magnified.|
|NSECTION||12||Number of equally-spaced sections to be considered in finding critical moments for beam design.|
|REINF||0||Column comfining reinforcement type:
Distance of face of support from start node of beam. Used for shear and torsion calculation.
|TRACK||0||Specify the level of detail in the output:
|WIDTH||ZD||Width of the concrete member. This value defaults to ZD as provided in the MEMBER PROPERTIES.|
