One method of connecting steel members is by using mechanical fastenings such as bolts and self-drilling screws, which are commonly used in cold-formed steel structures. The AIJ revised the “Recommendations for Design and Fabrication of Light Weight Steel Structures” this year, specifying the use of these mechanical fastenings. However, it is not permitted to combine different components in one joint. This study conducted real-scale tests to evaluate the ultimate strength of combined joints, and the results showed that it might be possible to sum the strength delivered from each component.
