      • Brick masonry arches are constructed using a series of wedge-shaped bricks, known as voussoirs, that are stacked on top of each other to form a curved shape. The center of the arch, known as the keystone, is the final piece to be placed and locks the arch into place.

    Figure 1 depicts examples of structural masonry arches used in contemporary construction. An arch is normally classified by the curve of its intrados and by its function, shape or architectural style. Figure 2 illustrates some of the many different brick masonry arch types.

    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 ...

    Figure-1.-Arch-Terminology Technical Notes 31, 31A and 31C address the structural design of brick masonry arches. Design methodology and example calculations are provided for jack, segmental and semi-circular arches. The reader should refer to these Technical Notes for specific design recommendations. 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...

  4. An arch is composed of small elements such as bricks bonded in mortar. It works by transferring the load sideways and downwards, from the key stone at the centre to the jambs of the walls below.

  5. Mar 17, 2021 · Synopsis: Mason John Carroll walks through the process of building four semicircular brick arches for the support structure under an addition. Step-by-step photographs depict building and setting the forms, laying the first and subsequent courses, revealing the inner arch, and finishing the joints. Carroll explains how to calculate the brick ...

  6. Feb 1, 2018 · The arch is the most common, traditional method of spanning openings with masonry. The arch makes use of the high compressive strength inherent in masonry and, with proper geometry, doesn’t need reinforcing or supplemental support. The arch is an aesthetically pleasing form and one that just looks “right” in masonry.
