LITERATURE SURVEY OF WEB CRIPPLING EXPERIMENT ON CEE-SHAPED SPECIMENS WITHOUT PERFORATIONS

Cold-Formed Steel (CFS) products are widely used in the field of building construction due to their inherent characteristics such as high material strength and design versatility. Depending upon their application and loading configuration, these structures are prone to different types of failures. Web crippling is a type of localized failure mode observed in CFS beam structures due to concentrated loading over them. The web crippling behavior in CFS products are influences by various factors including geometric, material, loading and environmental properties, making it a complex failure phenomenon. This literature survey investigates ten research studies performed on Cee-shaped CFS specimen, focusing on various dimensions and loading configurations. By examining the experimental and analytical methodologies considered across various studies, the paper attempts to consolidate the key findings which could propose future researches. The survey offers an insight into discrepancies in the design practices for predicting the ultimate web crippling strength in Cee-shaped Cold-Formed Steel specimens.
