The combined effect of forces from moment and shear should be considered while designing fasteners or welds for end connections of girders, beams, and trusses. When flanges or moment connection plates for end connections of beams and girders are welded to the flange of an I- or H-shape column, a pair of column-web stiffeners having a combined cross-sectional area A_st not less than that calculated from the following equations must be provided whenever the calculated value of A_st is positive

Bearing Stiffeners as Column:

Bearing stiffeners are structural components that are used to reinforce the connection between a beam and a column in a building or bridge. They are designed to transfer the load from the beam to the column while also providing additional support and stability to the structure.

The function of bearing stiffeners is to:

1. Prevent the beam from buckling or collapsing under the weight of the load it is carrying.

2. Distribute the load evenly across the column to prevent any localized stresses that could cause damage to the structure.

3. Increase the overall strength and stiffness of the connection between the beam and column.

4. Reduce the deflection of the beam and minimize any movement or displacement of the structure.

Bearing stiffeners are typically made from steel or concrete and are installed at the ends of the beam where it meets the column. They can take many different shapes and sizes depending on the specific application and design requirements.

In summary, bearing stiffeners are an essential component of any building or bridge structure. They play a critical role in ensuring the safety and stability of the structure by providing additional support and reinforcement to the connection between the beam and column.
