Design Of Plate  Girder : Program Info./Limitations
Structural steel design is as per Indian Standard No.IS:800-2007.
The plate girder compound section consists of two angles each  placed at top & bottom, flange plates at top and bottom of angles, and  ISMC section  placed  at top and bottom of flange plates. All Webs are assumed as un-stiffened. Gap between web plate and top flange angles is assumed as 10 mm.
Actual deflection value is increased by 10 % , to account for any concentrated  load.
Only following ANGLE and ISMC members are used in design.
