Question
Download Solution PDFConsider the following statements with respect to proportioning of flanges in a plate girder and identify the correct option.
Statement A: When the moment-resisting capacity of a plate girder is to be increased, the flange cover plates may be provided over the flange angles.
Statement B: The flange plates shall be thicker than the flange angles in a riveted/bolted plate girder.
Answer (Detailed Solution Below)

- When moment resisting capacity of the plate girder has to be increased, flange cover plates are provided over flange angles. The moment of inertia and consequently the moment resisting capacity of the girder is increased considerably as the flange cover plates are at the greatest distance from neutral axis.
- The flange cover plates should not be thicker than the flange angles in riveted/bolted connections. Hence, if necessary more than one plate may be required. It is preferred that all cover plates should have same or less thickness than flange angle.
Hence statement A is correct and statement B is incorrect.
