Iron+and+steel

“the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics” This is [|John H. Lienhard] quoting Swinbourne in his text IRON BUILDINGS. He was trying to explain that iron (as a construction material) start to vanish not only for the advantages of other materials like steel which permit to to build far taller buildings, offering better support and other advantages. For example steel is uniformly strong, elastic, and workable, and its high resistance in all stresses (tension, compression and bending) can be closely calculated. Probably, the principal cause of this changes was produced for building facilities but the new trends and styles influenced enormously. In my opinion, environmental change based on Physiological human needs should be stronger than psycological but no one can deny that the desire to fullfil both is something that worth striving for.
