    Segmental Arch Bridge Designs

    Segmental arches require care in laying the arch, but can also be used to great advantage, particularly where the stream being spanned is a rock-walled gorge.

    The Stone Slab Bridge

    Stone slab culverts represent an early and simple way to bridge a gap with stone. However, due to the inherent structural weakness of this design, only small spans are practical, demonstrating the advantages of the arch.

    Load Distribution Within the Arch

    The arch tends to gradually spread narrow loads over a larger area as the forces travel though the arch. In this post we outline why this is and some implications of this fact.

    The Spandrel Wall and the Arch

    Stone arch bridges feature spandrel walls in order to create a reasonably level roadway. These walls, however, are also an important structural part of the bridge, allowing it to carry heavier loads.

    Structural Considerations of Low-Rise Arches

    Low-rise arches make for daring designs with minimal “humps” in the road. However, there are certain structural considerations that need to be seriously taken into account when designing a low-rise arch.

    Pros and Cons of Mortarless Masonry

    Mortarless masonry has several construction advantages over its mortared counterparts. However, with these advantages come a greater precision and skill required for long-term durability.

    The Middle-Third Rule

    The middle-third rule is a classic rule in masonry design. In this post we explain what this rule is, why it is associated with stability, and how it is derived, as well as its limitations.

    Masonry: Always Moving

    Gravity, aided by natural forces like freeze/thaw cycles, is always at work on a masonry structure either pushing it more firmly in place or pulling it apart. By working with these forces, better structures can be built.
