The Finite Element Analysis on Axial Tensile Bearing Capacity of Round Steel-tubes Reinforced with CFRP Sheets XiuLi Wang1,a, JunJie Li1,b 1School of Civil Engineering, Lanzhou University of Technology, Lanzhou 730050, P.R.
Now, the theory research and engineering applications in relation to CFRP reinforcement technique are mainly concentrated in the aspects of concrete structure and masonry structure reinforcenment.
However, this technology still be studied rarely in the field of steel structure reinforcement, and related engineering applications are hardly any.
