Structural Performance of Experimentally Investigated CFRP-Strengthened Cold-formed Steel Built-Up Columns
https://orcid.org/http://orcid.org/0000-0002-8308-729X
This paper presents the investigation on built-up cold-formed steel column sections strengthened with carbon fibre-reinforced polymer (CFRP). Here, box-shaped column sections were fabricated by screwing together with individual channels. Behaviour of twelve plain and twelve CFRP-strengthened box sections was studied under axial compression. Three lengths of 300 mm, 500 mm and 700 mm with section thickness of 0.6 mm, 0.75 mm and 1 mm were studied in the investigation. The cold-formed steel design procedure suggested by North American specification AISI S100-16 and Euro code 3 (EC3) provisions was applied and compared with the experimental results, which were in good agreement. The results also indicate that the proposed strengthening technique is effective in repair and increasing the load-carrying capacity of cold-formed steel built-up box column.
