Mostly building are made from steel. Steel buildings are made up of repetitive framing of steel beams and columns. The beam column sequels are completely developed as a moment connection to withstand lateral loads. Lateral forces are transmitted by steel decking to the moment resisting frames. These frames of steel can be placed almost anywhere in the structure. Steel buildings are typically can be more flexible than wood buildings in their design and offers benefits of fire resistance, offsite fabrication of components and low expense. The building structural engineer must ensure their designs combine all the criteria of desired load, safety, architectural, serviceability and performance.
