Screwed connections in built-up cold-formed steel members at ambient and elevated temperatures

Screwed connections are commonly used in fabricating built-up cold-formed steel (CFS) members. However, the knowledge and understanding of their behaviour design limited. This research study investigated shear capacity screwed CFS It included a series tests between two single channel members as back-to-back members, failing by tilting bearing. Tests were conducted at both ambient elevated temperatures. Using results from these available literature, this has shown that equations for bearing current standards reliable temperature. then same can be to predict temperatures if they combination with proposed reduction factor temperature capacities. Details study, its findings presented paper.
