Several types of floor systems can be integrated with cold-formed steel stud walls to form a suitable hybrid system for mid-rise load bearing construction. Hollow-core concrete planks offer the advantages of high stiffness-to-weight ratio, rapid field installation, and the longest design spans. The recent advances in cold-formed steel load bearing walls to be integrated with the hollow-core plank system include the development of stronger studs and stiffer lateral bracing members. The development of connection details and simplified design tools are also key elements to make this sytem integration a successful process.
