General Principles of Bonding
The arrangement of bricks when building, is of great importance, as upon this depends the strength and appearance of the work


Wall without Bond
Fig. 7 - Volume 4, page 157
Consider Fig.7, it is clear that a wall built in this manner would tend to split along the continuous vertical joints,
if subjected to any irregular strain

Cavity Walls
In bleak and exposed situations, subject to driving rain and snow, the external walls of buildings are frequently built with a space in their thickness, usually 2" wide, to prevent penetration of dampness into the interior of the building

Near the sea, the spray carried by the wind, deposits salt on the face of the walls, and this permanently attracts moisture from a humid atmosphere

Isolated Piers
Receiving no support from abutting walls, these need to be of a greater sectional area than connected piers

Their height is relative to their sectional area, owing to brickwork's liability to buckle under its own weight, as well as the applied load

Load on a arch

The load carried by an arch is the triangle of brickwork contained within the offsets, shaded in grey

In a segmental arch, this covers the entire span

With a semi-circular arch, it is shown by the tangents to the curve
