Steel structures refer to buildings or infrastructure that are constructed primarily using steel as the primary material for the load-bearing elements. Steel is a versatile and durable material that is commonly used in construction due to its high strength-to-weight ratio, fire resistance, and ability to be fabricated into various shapes and sizes. Research in the field of steel structures focuses on optimizing design, construction, and maintenance practices to enhance the performance, safety, and sustainability of steel buildings. This includes studying new materials and technologies, improving structural analysis and design methods, analyzing the behavior of steel structures under different loading conditions, and developing innovative construction techniques. Overall, research in steel structures aims to advance the field of structural engineering to create safer, more resilient, and more efficient buildings and infrastructure.
