In earthquake - prone areas, angle steel can play an important role in seismic - resistant construction. Its good mechanical properties, including high strength and ductility, enable it to absorb and dissipate seismic energy. When used in building structures, angle steel can be incorporated into the seismic - resistant framework, such as diagonal braces and frame connections. The L - shaped cross - section provides flexibility and deformation ability, allowing the structure to withstand the dynamic loads and vibrations caused by earthquakes without collapsing immediately. However, special seismic - design considerations, such as proper connection details and reinforcement, are necessary to ensure its effectiveness in seismic - resistant applications.
