Effective Use of Drift Joints in Exterior CFS Walls

by Kirsten Zeydel, S.E.

July 27, 2021; 11:00 AM - 1:30 PM Pacific Time

ICC Preferred Provider Course Number: 11438

Seminar Description

Horizontal drift joints in exterior facades have become a common practice for addressing the expected lateral drifts of building structures due to wind and seismic loads. The intent of these joints is to reduce damage to the exterior façade components during wind and seismic events. Unfortunately they are usually located by the architect and frequently not coordinated with other façade systems or even within the CFS wall system itself. This web seminar will address effective ways to use drift joints and common mistakes that occur with the use of drift joints in exterior CFS wall systems.

It will also cover the following topics:

• The various cold-formed steel drift joint assemblies being used
• How the joints do or don’t work with the exterior finish
• What happens at adjacent façade systems
• What happens at building corners and building offsets

Common problems that drift joints create with other architectural and MEP components. Examples will be provided to illustrate these concepts including 2-D and 3-D diagrams.

Speaker Bio

She is a licensed Structural Engineer, based in Southern California, with over twenty years of experience in the design of cold-formed steel framing. She has led the structural design of exterior/interior non-load-bearing and load-bearing cold-formed steel framing for buildings across the United States. She has also successfully taken many projects through the rigorous California Office of Statewide Health Planning and Development and the California Division of the State Architect. In practice, Kirsten Zeydel specializes in panelized cold-formed steel construction and the design/coordination of exterior building “skins” in order to ensure they perform as expected during earthquakes and wind events.
