SGrade choices are "N"=Normal strength or "H"=High strength.

 

Units choices are "A"=Actual or "R"=Ratio.

 

LoadHeight choices are "C"=Shear centre or below or "T"=Top flange.

 

CalcLcMjr choices are "Y"=Calculate LcMjr from a buckling analysis or "N"=Use the input value of LcMjr.

 

BraceMjr choices are "Y"=Both ends of the design group are braced in position for buckling about the major axis or "N"=Either or both ends of the design group are not braced in position for buckling about the major axis.

 

CalcLcMnr choices are "Y"=Calculate LcMnr from a buckling analysis or "N"=Use the input value of LcMnr.

 

BraceMnr choices are "Y"=Both ends of the design group are braced in position for buckling about the minor axis or "N"=Either or both ends of the design group are not braced in position for buckling about the minor axis.

 

CalcLb choices are "Y"=Calculate Lb+ and Lb- from the flange restraints or "N"=Use the input values of Lb+ and Lb-.

 

TopPos and BotPos are lists of the intermediate flange restraint positions which can include @ multipliers but not dashes. For example, restraint positions 1.2,3.0,4.8,6.6,8.4,10.2,11.4 could be listed as 1.2,5@1.8,1@1.2 or 1.2,5@1.8,11.4.

 

TopRest and BotRest must be a string of characters without commas, dashes or @’s. For example FLLPLR.

 

Ast choices are "A"=Single angle, "S"=Double angle with short legs connected, "L"=Double angle with long legs connected or "X"=Double starred angle. Ast is only considered if the section is an angle section.

 

EndCon choices are "C"=Centroid, "F"=Flange, "W"=Web, "S"=Angle short leg or "L"=Angle long leg.

 

EccEffect choices are "Y"=Consider end connection eccentric effects or "N"=Ignore eccentric effects.

 

Criteria choices are "W"=Use weight design criteria or "D"=Use depth design criteria.

 

ISSeismicCat choices are 0=Non-seismic, 1=Ordinary concentrically braced frame, 2=Special concentrically braced frame, 3=Ordinary moment frame or 4=Special moment frame.

 

NZSeismicCat choices are 0=Non-seismic, 1=Category 1 member, 2=Category 2 member, 3=Category 3 member or 4=Category 4 member.

 

MemberType choices are 0=Non-specific, 1=Beam, 2=Column or 3=Brace.

 

Cantilever is reserved for a future version and should be set to 0.
