Cold-Formed Steel Design
John C. Huang, Ph.D., PE
Cold-Formed Steel (CFS) has been widely used in many areas of engineering, from civil to mechanical to structural. In recent years, the use of cold-formed steel in both commercial and residential construction has been increased significantly. This course provides general guidance on the cold-formed steel design to engineers, architects, and contractors. It consists of four parts: 1. An overview of cold-formed steel structures, which discusses the manufacturing process of CFS, industry standard nomenclatures, and CFS applications in today's construction market. 2. Review of the mechanical properties of CFS and fundamental theories of cold-formed steel design. 3. Brick Veneer/Steel Stud Wall Design, which addresses the considerations and recommendations for the design, detailing, materials selection and construction of brick veneer/steel stud panel walls. 4. A Sample Project Discussion, which uses a six-story apartment building with load-bearing stud walls as an example to illustrate the design concepts and procedures for X-braces.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
At the conclusion of this course, the student will:
Cold-formed steel is one of the most common building materials for commercial and residential structures. The building systems and components made from cold-formed steel offer many benefits, such as attractive appearance, high strength-to-weight ratio, high resistance to water penetration, low thermal transmission rate and low maintenance.
Although the project architect is responsible for the detailing of building interiors and exteriors, it is beneficial for structural, mechanical and electrical engineers to have a thorough understanding of the entire building system. Besides, the structural engineer of record is often responsible for establishing the following design criteria for the cold-formed steel building systems and components:
1. Building Code and Year
2. Wind Speed
3. Building Category or Importance Factor
4. Building Exposure
5. Deflection Limitation
6. Minimum Material Thickness
For non-load bearing walls, slide connections are usually required at or near the top of studs. There are several types of slide clips on the market. The innovative Verticlips distributed by The Steel Network offer solutions for many different applications.
For load-bearing studs, the designer shall emphasize the importance of direct bearing between stud and webs of top and bottom tracks. In other words, no gap is permitted at the top and bottom of load-bearing studs.
