List Of Arches And Bridges In Central Park
Central Park in New York City has thirty-six ornamental spans, most of which were built in the 1860s as part of the park's construction. No two bridges in the park are alike.Henry Hope Reed, Robert M. McGee and Esther Mipaas''The Bridges of Central Park.''(Greensward Foundation) 1990. There were three types of bridges and arches constructed in Central Park. The spans across the sunken "transverse" roads that carry crosstown traffic below the park were made of natural-looking schist, and are generally not counted as arches or bridges. "Ornamental Bridges or Archways" were larger spans integrated into the greater landscape and were made of brick, stone, or cast iron. The final category, "rustic" bridges, were smaller stone or log bridges and usually spanned small walkways or streams. Central Park had 39 bridges at its peak. The bridges were devised as part of Frederick Law Olmsted and Calvert Vaux's proposal for Central Park, the Greensward Plan. Most of the spans were built in the ...

Bridle Path
A bridle path, also bridleway, equestrian trail, horse riding path, ride, bridle road, or horse trail, is a trail or a thoroughfare that is used by people riding on horses. Trails originally created for use by horses often now serve a wider range of users, including equestrians, hikers, and cyclists. Such paths are either impassable for motorized vehicles, or vehicles are banned. The laws relating to allowable uses vary from country to country. In industrialized countries, bridle paths are now primarily used for recreation. However, they are still important transportation routes in other areas. For example, they are the main method of traveling to mountain villages in Lesotho. In England and Wales a bridle path now refers to a route which can be legally used by horse riders in addition to walkers, and since 1968, by cyclists. A "ride" is another term used for a bridleway: "a path or track, esp. one through a wood, usually made for riding on horseback" (''Oxford English Dicti ...

Claremont Riding Academy
The Claremont Riding Academy, originally Claremont Stables, 175 West 89th Street, between Columbus and Amsterdam Avenues on Manhattan's Upper West Side, was designed by Frank A. Rooke and built in 1892. Closed in 2007, Claremont was the oldest continuously operated equestrian stable in New York City and the last public stable in Manhattan. The building was listed on the National Register of Historic Places in 1980 and designated a New York City Landmark in 1990. Since 2010, it has belonged to the Stephen Gaynor School. Claremont Stables In 1892, when horses still provided the primary means of transportation – the first automobile appeared on Manhattan's streets six years later – developer Edward W. Bedell, architect Frank A. Rooke, and builder Richard Deeves created a four-story carriage stable with a full basement. A penthouse was added in 1901. The structure had stalls for horses on the basement and second floors, and carriage storage space on the third, fourth, and pe ...

Span (engineering)
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the stress) will quadruple, and deflection will increase by a factor of sixteen. For long-distance rope spa ...

Vault (architecture)
In architecture, a vault (French ''voûte'', from Italian ''volta'') is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed. Vault types Corbelled vaults, also called false vaults, with horizontally joined layers of stone have been documented since prehistoric times; in the 14th century BC from Mycenae. They were built regionally until modern times. The real vault construction with radially joined stones was already known to the Egyptians and Assyrians and was introduced into the buil ...

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Brownstone
Brownstone is a brown Triassic–Jurassic sandstone that was historically a popular building material. The term is also used in the United States and Canada to refer to a townhouse clad in this or any other aesthetically similar material. Types Apostle Island brownstone In the 19th century, Basswood Island, Wisconsin was the site of a quarry run by the Bass Island Brownstone Company which operated from 1868 into the 1890s. The brownstone from this and other quarries in the Apostle Islands was in great demand, with brownstone from Basswood Island being used in the construction of the first Milwaukee County Courthouse in the 1860s. Hummelstown brownstone Hummelstown brownstone is extremely popular along the East Coast of the United States, with numerous government buildings throughout West Virginia, Pennsylvania, New York, Maryland, and Delaware being faced entirely with the stone, which comes from the Hummelstown Quarry in Hummelstown, Pennsylvania, a small town outside of Har ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Bluestone
Bluestone is a cultural or commercial name for a number of dimension or building stone varieties, including: * basalt in Victoria, Australia, and in New Zealand * dolerites in Tasmania, Australia; and in Britain (including Stonehenge) * feldspathic sandstone in the US and Canada * limestone in the Shenandoah Valley in the US, from the Hainaut quarries in Soignies, Belgium, and from quarries in County Carlow, County Galway and County Kilkenny in Ireland * slate in South Australia Stonehenge The term "bluestone" in Britain is used in a loose sense to cover all of the "foreign," not intrinsic, stones and rock debris at Stonehenge. It is a "convenience" label rather than a geological term, since at least 46 different rock types are represented. One of the most common rocks in the assemblage is known as Preseli Spotted Dolerite—a chemically altered igneous rock containing spots or clusters of secondary minerals replacing plagioclase feldspar. It is a medium grained dark and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Wrey Mould
Jacob Wrey Mould (7 August 1825 – 14 June 1886) was a British architect, illustrator, linguist and musician, noted for his contributions to the design and construction of New York City's Central Park. He was "instrumental" in bringing the British High Victorian architecture to the United States, and was a founding member of the American Institute of Architects. Biography Born in Chislehurst, Kent in 1825, Mould attended King's College School in 1842. For two years, he studied the Alhambra in Spain under Owen Jones, the "master of polychromy," with whom he later co-designed the "Turkish Chamber" of Buckingham Palace. Mould's subsequent designs were often influenced by his appreciation of the Moorish style of architecture. Mould designed decorations for The Great Exhibition in London in 1851. He moved to the United States in 1852, and worked on the Crystal Palace Exhibition in Manhattan. He was invited by Moses H. Grinnell in 1853 to design and build Unitarian Church of All ...

The Ramble And Lake
The Ramble and Lake are two geographic features of Central Park in Manhattan, New York City. Part of Frederick Law Olmsted and Calvert Vaux's 1857 Greensward Plan for Central Park, the features are located on the west side of the park between the 66th and 79th Street transverses. The Ramble, located on the north shore of the Lake, is a forested area with highly varied topography and numerous winding walks, designated by the New York City Department of Parks and Recreation as a protected nature preserve. It was designed as a "wild garden" away from carriage drives and bridle paths, in which to be wandered, or to be viewed as a "natural" landscape. The Ramble includes several rustic bridges, and formerly contained a small cave. Historically, it has been frequented for both birdwatching and cruising. The serpentine Lake offers dense naturalistic planting, rocky outcrops of glacially scarred Manhattan bedrock, small open glades, and an artificial stream (the Gill) that emptie ...
