Seismic design incorporates various types of steel angle connections that are commonly utilized. These connections are specifically engineered to withstand the forces and movements experienced during seismic events. Several types of steel angle connections used in seismic design are as follows:
1. Bolted Flange Plate Connection: This connection involves the bolting of a steel plate to the flanges of two angle sections. It demonstrates excellent resistance against lateral and vertical forces while accommodating rotational movements.
2. Welded Flange Plate Connection: Similar to the bolted flange plate connection, this connection entails the welding of a steel plate to the flanges of two angle sections. It offers superior strength and stiffness but is less ductile when compared to the bolted version.
3. Extended Single Plate Connection: This connection is established by extending a single plate beyond the flanges of two angle sections and welding it to both flanges. It provides commendable resistance against lateral and vertical forces while accommodating some degree of rotation.
4. Double Angle Connection: In this connection, two angle sections are joined together using bolts or welds. It possesses high strength and stiffness, effectively resisting lateral and vertical forces.
5. Diagonal Brace Connection: This connection involves connecting diagonal braces to the flanges of two angle sections. It enhances resistance against lateral forces and effectively controls building sway during seismic events.
6. Gusset Plate Connection: This connection employs a gusset plate to connect two or more angle sections. It demonstrates good strength and stiffness while effectively resisting lateral and vertical forces.
Each of these steel angle connections possesses its own advantages and disadvantages. The choice of connection relies on factors such as structural design requirements, loadings, and the level of seismic activity in the region. It is crucial to carefully consider these factors and seek consultation with structural engineers to ensure the appropriate connection type is employed for a seismic design project.

There are several types of steel angle connections commonly used in seismic design, including bolted angle connections, welded angle connections, and moment-resisting angle connections. Bolted angle connections involve connecting angles together using bolts, providing flexibility and ease of installation. Welded angle connections involve welding the angles together, creating a strong and rigid connection. Moment-resisting angle connections are designed to resist bending moments and provide enhanced resistance against seismic forces. These connections typically combine elements of both bolted and welded connections to achieve optimal strength and flexibility.
