The spelling of the word "skew arch" may be confusing at first glance. "Skew" is spelled as /skjuː/ in IPA phonetic transcription, which represents the sound of "sk" followed by the "yoo" vowel sound. "Arch" is spelled as /ɑːrtʃ/, with a long "a" sound followed by the "ch" sound. Together, the word is pronounced /skjuː ɑːrtʃ/. A skew arch is a type of masonry arch that is built at an angle other than a right angle to the abutments.
A skew arch is a type of architectural arch that is constructed at an angle other than 90 degrees to its abutments or supports. Unlike typical arches, which are usually built perpendicular to the direction of the force they bear, skew arches are designed to accommodate oblique or skewed loading conditions, often arising from the alignment of roads or railways.
The distinguishing feature of a skew arch is its non-perpendicular orientation relative to its supports. This skew or oblique angle creates a more challenging and complex construction process compared to conventional arches. Skew arches are commonly used to bridge gaps over roads or railways where multiple intersections or divergent paths require an arch to be built at an angle to effectively distribute the loads.
The construction of a skew arch involves careful calculations and modifications to ensure structural integrity and stability. The arch is designed to withstand the lateral forces imposed by the skew angle and the weight of the loads it carries. Materials commonly used for skew arch construction include stone, brick, concrete, or steel.
Skew arches have been used in various architectural styles throughout history, with notable examples seen in ancient Roman, Gothic, and modern engineering structures. Their unique design and ability to accommodate skewed loading conditions make them an important architectural solution in transportation infrastructure and civil engineering projects.
The word "skew" comes from the Old Norse word "skewr" or "skjota", which means "to shoot" or "to project". It later evolved to refer to something that is not straight or aligned, especially at an angle or oblique.
The word "arch" can be traced back to the Latin word "arcus", which means "bow" or "arch". In architecture, an arch is a curved structure that spans an opening and supports weight, creating a stable and symmetrical construction.
When these two words are combined, "skew arch" refers to an arch that is not aligned with the perpendicular or at a right angle to its supporting walls or foundations. A skew arch is constructed obliquely to the axis of the supporting structure, typically to accommodate an oblique or skewed axis in the overall architectural design.
