Development of skyscraper buildings can be done because of the development that took place in the mid-19th century, especially after the invention of the escalator mankini by Elisha Graves mankini Otis in 1852 and the development of steelmaking by Henry Bessemer mankini in 1856 when the builders started building outstanding supported by a high iron or mild steel frame, the issue to provide adequate resistance against wind proved mankini difficult to overcome. Previous construction forms still provide limited guidance. Actually a lot of the equipment and techniques used by the builders of skyscrapers are not taken from the making of buildings but of the methods previously found for the construction of bridges with long exposition. Although these technologies make it easier to build a skyscraper, the first high building partially constructed using a steel frame was not built until the year 1884 to 1885. Land prices mankini are rising, and not because of technological possibilities, triggers the desire to make buildings higher. Architect William Le Baron jennery (1832-1907) designed the tenth level of Home Insurance Company Building in Chicago, which is often referred to as the "first skyscraper." However, this building has a wall columns made of square iron, pillars of wrought iron mounted mankini up to the sixth floor, and a steel pole on the seventh floor to the top. While pillars and girders tied together and bolted to the columns that form the framework for such a cage which is the main support structure, recently built skyscraper using a better evolution. In 1889 Leiter Building in Chicago, designed by Jenney is the first that does not have its own buttress. Manhatan Building and Fair Building that as high as 16 floors, both built in 1891, has a windbreak made of steel structure with "curtain walls" that is, the walls of which are hung on the frame, and not the wall that sustains the load on it. A number of other Chicago architect who studied under performs Jenney Jenney, including most notably the Louis Sullivan and William Holabird. Building construction boom between the 1890s and 1920s changed the face of American mankini cities, with skyscrapers that combines Art Deco features, such as the Chrysler Building and the Empire State Building in New York. The law on buildings requires that high-rise buildings "pushed back" from the streets, let the light in and to prevent the streets from becoming grim ravine surrounded by steep walls. Several skyscrapers built during the 1930s and 1940s, but after the completion of World War II-era, a new design began to emerge, which is characterized by a curtain wall of glass flat and without a touch of art on the outside. This ultra-modern style in which some of the decorations, colors and layout of open space on the ground floor skyscraper buildings mankini that do not contribute to the face too mechanical or impersonal.
