Purpose: Used to define the grade of steel.
--> Given in girder input. Also given in bracing input in Girder System Projects.
Steel grade is specified as follows:
A36 STEEL* (Default)
A514 STEEL
A7 STEEL
A572 STEEL (Note: A572 is grade 50)
A588 STEEL
A852 STEEL
M270-36 STEEL
M270-50 STEEL
M270-50W STEEL
HPS-50W STEEL (LRFD only)
HPS-70W STEEL
M270-100 STEEL
M270-100W STEEL
M183 STEEL
M222 STEEL
M223 STEEL
M244 STEEL
M270M-250 STEEL
M270M-345 STEEL
M270M-345W STEEL
M270M-485W STEEL
M270M-690 STEEL
M270M-690W STEEL
Alternatively, girder steel can be given by strength and by web section (see FYTF , FYBF , FYW , FYS , FYBSPL , FYTSPL , FY )
Note: use of the condition STEEL for a given web section will override any other data involving steel strength for that web section, including STIFFENER STEEL. So to use the STIFFENER STEEL condition effectively it must be accompanied by the WEB STEEL , TOP FLANGE STEEL , and BOTTOM FLANGE STEEL conditions.
(Also see definitions of the following conditions: TOP FLANGE STEEL , BOTTOM FLANGE STEEL , WEB STEEL , STIFFENER STEEL , FOR SECTION i, j, … )
