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?
