The Marshall Building, formerly known as the Hoffman & Sons Co. Building, is a historic building in Milwaukee, Wisconsin, United States.Part of the Historic Third Ward, the six-story building is the oldest existing example of structural engineer Claude A. P. Turner's Spiral Mushroom System of flat-slab concrete reinforcement.
In classical architecture, the shape of the abacus and its edge profile varies in the different classical orders. In the Greek Doric order, the abacus is a plain square slab without mouldings, supported on an echinus. [2] In the Roman and Renaissance Doric orders, it is crowned by a moulding (known as "crown moulding").
He formed his own company in 1901 and received a patent in 1908 for an innovative flat-slab support system, known as the Turner System or the Spiral Mushroom System, using reinforced concrete, although this patent was invalidated in 1915 and 1916 in favor of similar patents filed by American engineer O.W. Norcross.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
America's Favorite Architecture" is a list of buildings and other structures identified as the most popular works of architecture in the United States. In 2006 and 2007, the American Institute of Architects (AIA) sponsored research to identify the most popular works of architecture in the United States.
Octagonal buildings and structures are characterized by an octagonal plan form, whether a perfect geometric octagon or a regular eight-sided polygon with approximately equal sides. Octagon-shaped buildings date from at least 300 B.C. when the Tower of the Winds in Athens , Greece, was constructed.
5-over-1 or over-1s, also known as a one-plus-five or a podium building, [1] is a type of multi-family residential building commonly found in urban areas of North America. [ 2 ] [ 3 ] The mid-rise buildings are normally constructed with four or five wood-frame stories above a concrete podium, usually for retail or resident amenity space.
Flat slab subduction is characterized by a low subduction angle (<30 degrees to horizontal) beyond the seismogenic layer and a resumption of normal subduction far from the trench. [1] A slab refers to the subducting lower plate. A broader definition of flat slab subduction includes any shallowly dipping lower plate, as in western Mexico.
