5. Review of Previous Presentation Steel Structures  A steel building is a metal structure fabricated with steel for the internal support and for exterior cladding, as opposed to steel framed buildings which generally use other materials for floors, walls, and external envelope.structure steelsteel framed Or,  A structure which is made from organised combination of structural steel members designed to carry loads and provide adequate rigidity.

6. Review of Previous Presentation Design Wind Speed Design Wind Speed – Design wind speed is the wind speed at any height taken for the design of high rise buildings (greater than 10m). It is denoted by V z. Though wind speed vary for innumerable reason and vary from place to place and height. IS 875(Part 3)–1987 consider only 4 numeric factors 1) Design wind speed = V b *K 1 *K 2 *K 3 2) K 1 = Probability or Risk Factor 3) K 2 = Roughness and Height factor 4) K 3 = Topography Factor Page No - 6
