Lesson Category: Assessment, Maintenance, and Repair of Transitional Masonry Structures Series
This session discusses the typical masonry exterior wall systems, commonly referred to as transitional masonry wall systems and how to identify them. These wall systems combine aspects of both load-bearing masonry and modern curtain wall systems having structural frames. The unique features of such construction are examined along with how these systems work structurally, how they deteriorate, and how they manage water, temperature, air, and vapor transmission.…
