A simply supported welded plate girder of span 25m is subjected to service load of
60kN/m UDL and two fixed point loads of 250 kN each spaced at 8.5m from each
supports. Design the plate girder cross section. Provide all required checks for cross section as per IS code provision. Apply curtailment of flanges.

Design a suitable section for gantry girder for the following data:
Crane capacity = 250 KN, Span of the crane girder = 8 m, Self weight of the crane girder excluding trolley = 200 KN, Self weight of the trolley = 50 KN, Minimum hook approach = 1.25 m, Wheel base of crane = 3.5 m, Self weight of rail section = 300 N/m. Assume no lateral retraining along the span. Provide checks for B.M and deflection only.
