Cold-Formed Steel X-Brace Design
Course Outline
X-braces are one of the most commonly used lateral bracing systems for cold-formed steel structures. This course provides detailed guidance on the design and detailing of steel strap X-braces, from wind pressure calculations to lateral drift analysis to connection design. A six-story apartment building with load-bearing stud walls is used as an example to illustrate the design concepts and procedures for X-braces. Typical details are also presented for both light duty and heavy duty applications. This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
