Abstract:

Advances in the field of finite element analysis software in the past 50 years have been quite extensive and have led to considerable benefits in research industry, mainly for composite structures. In this paper, finite element analysis was carried out to investigate the failure modes and axial capacity of CFRP strengthened cold formed steel lipped channel sections. A total of 27 test cases were analyzed using FEA software and results were compared with capacities recorded from the experimental tests. The results indicate that the proposed FEA modeling with material properties can be used to calculate the axial capacity of CFRP strengthened cold formed lipped channel sections.
