ABC109 Differential Movement and Expansion Joints in Brick Veneer

Understanding the mechanical properties of brick and brick veneer construction is crucial when it comes to designing buildings capable of withstanding the tests of time, and few factors are more important to consider than differential movement, or the differing rates of expansion and contraction between brick and the supporting structure.

Designed primarily for architects—but also containing potentially useful information for engineers—this course explains how changes in temperature and moisture cause brick and other building materials to move at different rates, as well as how to account for this phenomenon by way of properly spaced expansion joints.

• Learn how temperature and moisture changes cause brick and other materials to move at different rates.
• Learn difference between concrete masonry control joints and brick expansion joints.
• Receive practical guidelines for placing expansion joints in brick veneer.
• Learn the proper construction of expansion and control joints.
