Q1: Consider the following statements in respect of plate girders :
1. A large number of cover plates are provided over flange angles so that curtailed flanges match the bending moment diagram exactly.
2. At least one cover plate should extend over the entire span so that rain water may not enter and corrode the connections.
3. A minimum of one-third of flange area should be provided in flange angles and balance in flange cover plates for stability.
Which of the statements given above are correct ?
