Steel Structures

Steel Structures is a specialized field within Civil Engineering that focuses on the design, analysis, and construction of structures using steel as the primary load-bearing material. This discipline involves applying principles of structural mechanics and materials science to create a wide range of infrastructure, including high-rise buildings, long-span bridges, industrial warehouses, and towers. Engineers in this field select appropriate steel shapes and connection types (such as bolts or welds) to ensure that the structure can safely resist forces like tension, compression, and bending, leveraging steel's high strength-to-weight ratio, ductility, and potential for prefabrication to build efficient and resilient systems.
