Investigation on stress profile of double bolted cold-formed steel channel beam

Abstract

Cold-formed steel sections are popular nowadays with a lot of advantages such as lightweight, thinner, less maintenance and ease to transport. With a lot of advantages, the study used two channels and bolted side by side to produce beam. The beam is established with symmetrical section and their strength investigated due to bending. The arrangement of the bolt is important to determine the relationship of the strength. In the study, there are 3 types arrangement of bolt spacing. The high stress illustrated in this study is recorded with bolt spacing 225 mm and end bolt spacing 230 mm. The stress showed lowest value when compared with hollow, solid section and reinforced concrete beam.
