D14.A.1 Design Parameters

The program contains a number of parameters which are needed to perform and control the design to SABS 0100-1. 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 of commonly used parameters for conventional design practice have been chosen as the basis. Table 17A.1 contains a complete list of available parameters with their default values.
Note: Once a parameter is specified, its value stays at that specified number until it is specified again. This is the way STAAD.Pro works for all codes.

Must be specified as SABS0100.

Design code to follow. See TR.53.2 Concrete Design-Parameter Specification.

BRACE 0.0

Column bracing:

  • 0. Column braced in both directions.
  • 1. Column braced about local Y direction only
  • 2. Column unbraced about local Z direction only
  • 3. Column unbraced in both Y and Z directions
CLB 20mm Clear Cover for outermost bottom reinforcement
CLS 20mm Clear Cover for outermost side reinforcement
CLT 20mm Clear Cover for outermost top reinforcement
DEPTH YD Depth of concrete member, in current units. This value default is as provided as YD in MEMBER PROPERTIES.
ELY 1.0 Member length factor about local Y direction for column design.
ELZ 1.0 Member length factor about local Z direction for column design.
FC 30N/mm2 Concrete Yield Stress / cube strength, in current units.
FYMAIN 450 N/mm2 Yield Stress for main reinforcement, in current units.
FYSEC 450N/mm2 Yield Stress for secondary reinforcement a, in current units. Applicable to shear bars in beams
MAXMAIN 50mm Maximum required reinforcement bar size Acceptable bars are per MINMAIN above.
MINMAIN 8mm Minimum main reinforcement bar size Acceptable bar sizes: 6 8 10 12 16 20 25 28 32 36 40 50 60
MINSEC 8mm Minimum secondary bar size a. Applicable to shear reinforcement in beams
TRACK 0.0
Specify the level of detail in the output:
  • 0) Beam design - Summary output, critical moment not printed. Column design - Summary output.
  • 1) Beam design - Detailed output, min/max steel% and spacing. Column design - detailed output.
  • 2) Beam design only - Details of reinforced section at sections defined by NSECTION parameter.
WIDTH ZD Width of concrete member, in current units. The default used the ZD value provided in MEMBER PROPERTIES.
