Consider the following statements: 1. The thickness of the gusset plate should not be more than the thickness of the structural members being connected. 2. A plate girder is essentially a beam and its moment of resistance depends upon its section modulus. 3. The function of the flanges in a plate girder is to resist the bending moment and hence their respective areas can be reduced near the supports of a simply supported beam. Which of the above statements are correct?

A

1 and 2 only

B

1 and 3 only

C

2 and 3 only

D

1, 2 and 3
