What benefit of steel structure buildings than concrete ??

Steel best earthquake zone compare to concrete and it is reusable

NOT economical in most of the cases.Advantages areFaster construction. Reduced deadload there by reduced substructure requirements.Improved headroom. Large column free area there by effective space utilisation. Better quality control over manufacturing of steel compared to concrete. Improved ductility of the structure there by enhanced resistance to earthquake and other dynamic loading.Improved fatigue strength there by better resistance to cyclic loading like traffic.Easy structural repairs. Easiness in structure dismantling and best re usability. Less environmental impact (find it how?clue? Processes in manufacturing of both)

Steel structures can be constructed quicker than concrete structures .. saves a lot of space since the x-sections will be defenitley smaller and it can cover large span roofs more efficiently compared to concrete elements.
