Introduction to Steel Design

The area of steel design is majorly concerned with the structural engineering domain, which is a specialization of civil engineering. Steel design is often known as structural steel design, whose primary concern is to design steel structures. The primary structure involves the designing and construction of frames using structural steel as the material. Residential buildings, houses, bridges, complexes, tall buildings, industrial warehouses, aircraft frames, frames of ships, and stadiums are some of the examples of structures that use steel framing.
