Definition
  1. Noun:
    • An arch whose height is less than half its width: A "diminished arch" is a specific architectural structure, a type of arch where the vertical distance from its highest point (the crown) to the level of its supports (the springing line) is less than 50% of the horizontal distance between those supports.
Usage

Advanced Usage
  • Technical Specification: In technical drawings and specifications, a "diminished arch" is defined by the precise ratio of its rise (height) to its span (width).
  • Structural Implication: This arch type distributes weight differently than a taller arch and may require different support considerations.
Variants and Related Words

  • Flat arch: A general term for an arch with little curvature; a diminished arch is a specific kind of flat arch.
