he design of steel structures involves the analysis and design of structural members such as beams, columns, tension members, compression members, and connections made of structural steel. Steel is widely used in construction due to its high strength-to-weight ratio, durability, ductility, and ease of fabrication and erection.
Steel structural design ensures that structures are safe, economical, and serviceable under various loads such as dead loads, live loads, wind loads, and seismic forces. The design process follows established design philosophies, primarily the Limit State Method, in accordance with relevant codes and standards (such as IS 800).
Key aspects include the determination of loads and load combinations, analysis of internal forces, selection of suitable steel sections, and design of connections using bolts or welds. Stability, strength, and serviceability requirements are carefully checked to prevent failure modes such as yielding, buckling, fatigue, and excessive deflection.
Overall, the design of steel structures plays a vital role in modern construction, especially in industrial buildings, bridges, towers, and multi-storey buildings, providing efficient and reliable structural systems.
