The various materials and elements that are used to construct a building are in a constant state of motion. All building materials change in volume due to internal or external stimuli. These stimuli may be changes in temperature, moisture, elastic deformations due to loads, creep, or other factors. Restraint of these movements may cause stresses within the building elements which in turn may result in cracks. To avoid cracks, the design should minimize volume change, prevent movement or accommodate differential movement between materials and assemblies. A system of movement joints can eliminate cracks and the problems they cause. Movement joints can be designed by estimating the magnitude of the several types of movements which may occur in masonry and other building materials. This Technical Notes describes the various volume changes in brick masonry and other building materials. It also describes the effects of volume change when the materials are restrained. Other Technical Notes in this series address the design and detailing of movement joints and the types of anchorage which permit movement.
