Yield Strength reduction as per Code

Indian Standard material code ( IS 2062 ) specifies reduction in Yield strength based on plate thk ( 250MPA for plate thk <20, 240MPa for 20<thk<40, & 230MPa for plate thk >40.)

Does staad pro takes this into consideration by default or one needs to specify FYLD parameter specially for plate fabricated beams & columns ?
