Ramping Arch
The ramping arch (also known as rampant arch, from , and raking arch) is an asymmetrical arch that has its Springer (architecture), springers located at substantially different heights. Frequently a ramping arch is associated with a ramp or stairs. Originally used to support inclined structures, like stairs or ramps, in the 13th-14th centuries the rampant arch appeared as parts of flying buttresses used to counteract the Thrust (arch), thrust of Gothic ribbed vaults, typical design was based on a truncated semicircular arch. Viollet-le-Duc in 1854 described two arch types in buttresses: the earlier one where the center of the intrados segment is located on the face of the wall (intrados close to a quarter-circle), and the later, more efficient, design where the center is moved inside the wall, narrowing the segment. The main purpose of a buttress is to relay the thrust to the Foundation (architecture), foundations, the structure also accommodates the downspouts. A typical flying bu ...

Two-tiered Arch
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have larger ...
