Graphical Construction Glossary >> masonry. >> arches >> Semicircular Arch
Also known as a roman arch this form is still popular today in certain areas. The Romans excelled at building huge aquaducts and viaducts using many arches in the length and up to thee tiers in height.
Making good use of the principle of one arch thrusting against another this series of arches has stood for nineteen hundred years.
This brick arch has some very fancy and complicated brickwork on the face, but to keep to a general theme of the building that has accents of Portland stone the soffit has been made out of curved ashlar work. Note how the returns of the string course form the imposts for the soffit stonework.
Another view of the same semicircular arch, this time showing the soffit stonework, which has saved some tricky brickwork.
