KY

1.0

 

K value in local y-axis. Usually, this is minor axis.

 

KZ

1.0

 

K value in local z-axis. Usually, this is major axis.

 

LY

Member Length

 

Length to calculate slenderness ratio for buckling about 

local Y axis.

 

LZ

Member Length

 

Same as above except in local z-axis.

 

FYLD

 

36 KSI

 

Yield strength of steel in current units. 

 

FU

NSF

1.0

 

Net section factor for tension members.

 

UNL

Member Length

 

Unsupported length of compression flange for calculating 

allowable bending compressive stress.

 

SSY

0.0

 

0.0 = Sidesway in local y-axis. 

1.0 = No sidesway

 

SSZ

0.0

 

Same as above except in local z-axis.

 

CMY 

CMZ

0.85 for sidesway

and calculated 

for no sidesway

 

Cm value in local y & z axes

 

MAIN

 

0.0

 

0.0 = check for slenderness 

1.0 = suppress slenderness check

 

RATIO

 

1.0
