A moment connection is a structural connection designed to transfer bending moments and shear forces between beams and columns, ensuring structural continuity and rigidity. Moment connections typically use flange and web plates that are bolted or welded to the members, allowing the transfer of forces while maintaining the stability of the overall frame. These connections are essential in resisting lateral forces and ensuring the structural integrity of frameworks, especially in high-rise buildings, bridges, and industrial applications.

The main components of a moment connection include:

• Flange Plate: Transfers bending moments from the beam to the column.
• Web Plate: Facilitates shear force transfer between members.
• Bolts: Secures flange and web plates to the beam and column.
• Welds: Used where a bolted connection is not suitable or for added strength.
• Beam and Column: Primary members in the framework that are joined via the connection.

These components collectively ensure the efficient transfer of strong-axis moment, vertical shear, and axial loads.

Moment connections are widely employed in structures that require enhanced rigidity and lateral force resistance. Typical applications include:

• High-rise buildings and commercial frameworks.
• Bridges and highway structures.
• Industrial plants and equipment supports.
• Warehouses and storage facilities.

The moment connection calculator is ideal for optimizing designs in these applications while ensuring compliance with code requirements.

In certain scenarios, alternatives such as simple shear connections or hinge connections may be considered. However, moment connections are the preferred choice when rigidity, lateral stability, and bending moment transfer are critical to the structural design.
