Right Answer is: B

SOLUTION

In plate girder, following assumptions are made while designing:

1. Bending stress in flanges is resisted by flange plates.

2. Vertical shear force is resisted by web.

3. Web buckling is resisted either by increasing thickness of web or by providing vertical stiffeners.

4. The horizontal shear force between the flange and the web plate is resisted by fillet welding.
