Abstract
This project presents a design method (BS5950-5) to predict the allowable load carrying capacity of cold formed steel channel section strengthened by carbon fibre reinforced polymer composites applied to the web of the beam. A specimen is presented to illustrate the proposed design approach. The validity of the proposed design method has been verified by comparing with the test results.
A concatenation of compression tests were conducted on plain and CFRP strengthened steel sections of different geometries. The strength of slender C-channel section varies with lengths; that are the longer the length of samples (mm), the lower the strength of samples (KN). The higher the slenderness ratio, the lower the strength of samples (KN) would be. This project also contains the consequences obtained by comparing the strengths of plain and CFRP strengthened steel columns using compression test. The findings showed that the strength of CFRP strengthened steel columns were up to 15% greater than plain cold form steel sections.
