A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. Sections of structural walls between openings (bays) can function as piers.
The pier of a bridge is an intermediate support that holds the deck of the structure. It is a massive and permanent support, as opposed to the shoring , which is lighter and provides temporary support.
A v-shaped rigid frame is an efficient way to support a longer bridge where using only one span isn't feasible. Each v-shaped pier supports the deck in two places while only requiring one foundation. The bending moments experienced in the piers are minimal, allowing significant reductions in the foundation size. [6]
A bent in American English is a transverse rigid frame (or similar structures such as three-hinged arches). Historically, bents were a common way of making a timber frame ; they are still often used for such, and are also seen in small steel-frame buildings, where the term portal frame is more commonly used.
A wooden footbridge using beams over a stream in Dordogne, France. Footbridge with steel construction over Böser Ellbach stream, Black Forest , Germany Since no moments are transferred, thrust (as from an arch bridge ) cannot be accommodated, leading to innovative designs, such as lenticular trusses and bow string arches , which contain the ...
A pier design uses a small, narrow building with aircraft parked on both sides. One end connects to a ticketing and baggage claim area. Piers offer high aircraft capacity and simplicity of design, but often result in a long distance from the check-in counter to the gate (up to half a mile in the cases of Kansai International Airport or Lisbon ...
A wooden pier in Corfu, Greece. A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piles or pillars, and provides above-water access to offshore areas. Frequent pier uses include fishing, boat docking and access for both passengers and cargo, and oceanside recreation.
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table.
