Reinforcement schemes for cold-formed steel joists with a large web opening in shear zone—An experimental investigation

The floor joists of cold-formed steel (CFS) structures often require large web openings. Reinforcement of such openings may mitigate the detrimental effects arising from such web openings. This paper is based on an experimental investigation conducted to establish reinforcement schemes for CFS joists with a large web opening located in high shear zones. The investigation considered a large web opening cut out in the middle of the web of a …
