The arch has long been used in masonry structures. In fact, a brick masonry arch found in the ruins of Ur in Mesopotamia dates back to 1400 B.C. Today, the brick arch is used in construction to span over wall openings and add aesthetics, as the arch is the consummate definition of form and function. This Brick Brief addresses design considerations ...

This Brick Brief discusses structural arch desi...
Non-structural arches require support by other elements. Many arches used today are non-structural, built purely for aesthetics. Structural support of the arch may be required because of insufficient arch or abutment strength or the lack of a structural analysis of the arch. Support is provided by a lintel which spans the opening or by a shelf angl...
Expansion joints in brick masonry can cause problems when arches are used in the building. Residential construction often does not require expansion joints because continuous wall runs are short. However, if an expansion joint is required near an arch, care must be taken not to affect the integrity of the arch. This is a common problem for very lon...
In residential construction, the presence of eaves, overhangs and small wall areas above openings will reduce the potential for water penetration at arch locations. However, flashing at an arch is just as important as over any other wall opening. Flashing an arch can be difficult, depending on the type of arch and the type of flashing material. Jac...
Both structural and non-structural arches must be properly supported throughout construction. Premature removal of the temporary support for a structural arch may result in a collapse of the arch. This is most often due to the introduction of lateral thrust on the abutment before proper curing has occurred. Out-of-plane bracing is required for all ...
The following is a list of rules of thumb which may be used when designing structural veneer arches. Jack Arches 1. Six foot maximum span without a lintel. 2. Larger skewback angle with longer span 3. Skewback = 1/2 in. per ft (4 mm per 100 mm) of span for each 4 in. (102 mm) arch depth 4. Camber of 1/8 in. per ft (1 mm per 100 mm) of span 5. Minim...
The segmental arch is a type of brick arch that has a shallow curve. It is one of the most common types of arches used in residential and commercial buildings due to its simplicity and ease of construction. The shape of the segmental arch is derived from a segment of a circle, which makes it relatively easy to construct using standard-sized ...
