What is a gusset plate?

A gusset plate is a steel plate that is used to connect beams and columns in a structural steel frame. It is typically made of either A36 steel or A572 steel and is welded or bolted to the beams or columns at the joint.

Gusset plates are used to provide additional support and stability to the frame, particularly at connections where the beams and columns intersect. They help to transfer loads and forces between the beams and columns, improving the overall strength and stability of the structure.

Gusset plates come in various shapes and sizes, depending on the specific requirements of the structure. They can be flat or curved, and may have holes for bolts or welds for attachment to the beams and columns.

In addition to structural steel frames, gusset plates are also commonly used in bridges, trusses, and other steel structures where additional support and stability is required. They play a crucial role in ensuring the safety and integrity of the overall structure.
