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.
The simplest cross section of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements.
Columns are a similar upright support, but stand on a round base. In buildings with sequence of bays between piers, each opening (window or door) between two piers is considered a single bay.
Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support the ends of spans between these abutments. In cold climates the upstream edge of a pier may include a starkwater to prevent accumulation of broken ice during peak snowmelt flows. The starkwater has a sharpened upstream edge sometimes called a cutwater. The cutwater edge may be of concrete or masonry, but is often capped with a steel angle to resist abrasion and focus force at a single point to fracture floating pieces of ice striking the pier. In cold climates the starling is typically sloped at an angle of about 45° so current pushing against the ice tends to lift the downstream edge of the ice translating horizontal force of the current to vertical force against a thinner cross-section of ice until unsupported weight of ice fractures the piece of ice allowing it to pass on either side of the pier.
A pier is a raised structure typically supported by well-spaced piles or pillars. Bridges, buildings, and walkways may all be supported by piers. Their open structure allows tides and currents to flow relatively unhindered, whereas the more solid foundations of a quay or the closely spaced piles of a wharf can act as a breakwater, and are consequently more liable to silting. Piers can range in size and complexity from a simple lightweight wooden structure to major structures extended over 1600 metres. In American English, pier may be synonymous with dock.
Piers have been built for several purposes, and because these different purposes have distinct regional variances, the term pier tends to have different nuances of meaning in different parts of the world. Thus in North America and Australia, where many ports were, until recently, built on the multiple pier model, the term tends to imply a current or former cargo-handling facility. In Europe in contrast, where ports more often use basins and river-side quays than piers, the term is principally associated with the image of a Victorian cast iron pleasure pier. However, the earliest piers pre-date the Victorian age.

Lecture date: 2005-10-25 'Trying to visualise today's practice of architecture and urbanism without the use of diagrams is an almost impossible exercise. Diagrams have incredible power to simultaneously construct, design, and expose an idea while at the same time, simplifying and idealising the complexity of the work into one simple sign. The diagram is "potential" but also "problematic" because it is constantly updating the representation of the work, and thus reducing it to an always-changing figure. The diagram, therefore, tends to be a very accessible consumption of events and things, a consumption of our experience of the world. My argument is that diagrams are not just a camouflage of reality or, as Witttgenstein would argue, a social constructed reality, but also (and especially) a...

Lecture date: 2017-05-11 The continuous use of certain specific motifs defines an architectural vocabulary, a particular language. This lecture will address FALA’s tropes. FALA is a naïve architecture practice based in Oporto, led by Filipe Magalhães, Ana Luisa Soares and Ahmed Belkhodja. Established in 2013, the atelier works with methodical optimism on a wide range of projects, from territories to birdhouses. FALA’s projects are a medley of formal languages, references, quotations, and themes, only regulated by an obsession for clarity; its architecture is both hedonistic and post-modern, intuitive and rhetorical. Filipe Magalhães (porto, 1987) graduated in architecture at Faculdade de Arquitectura do Porto and Fakulteta za Arhitekturo in Ljubljana; with a thesis titled ‘between the a...
Lecture date: 2013-10-16 A Brief History of Abstraction in Architecture: Design and the Administration of Life 'Let us hope that from time to time the individual will give a little humanity to the masses, who one day will repay him with compound interest.' Walter Benjamin, 'Experience and Poverty', 1933 Abstraction addresses the process of removal in order to reach the essential datum of things. In a design world increasingly dominated by organic and redundant forms, abstraction is likely to be one of the most unpopular concepts in the field of architectural theory. While it is a mistake to think abstraction opposes the complexities and contradictions of our world, we deny that it is the very outcome of larger historical and cultural forces. Pier Vittorio Aureli will investigate the...
