An improperly designed arch, like many other badly designed objects, just looks wrong to the eye. A properly designed arch both pleases the eye and can carry a heavy load without breaking.Caveat:
While this application will provide the factors necessary to accurately design a traditional arch shape, a true load bearing arch needs to be carefully constructed, taking into account many other factors, such as foundation design, strength of the material used to build the arch, overburden, static and dynamic loads, and professional construction techniques.
1. The tallest common Gothic arch's radius is no more than twice the span of the arch.
2. To prevent failure, a segmental arch must have a rise (height above springline) that is equal to at least one-eighth the width of the span. Segmental arches with a rise that is less than one-eighth of the span width must have a permanent support or frame beneath the arch to prevent failure.
EXCEPTION: The thickness of a flat arch must itself encompass a stable arch (for a given width, thickness must be at least width divided by 8).
