High modulus carbon fiber materials for retrofit of steel structures and bridges
This paper summarizes the research work dealing with the use of high modulus carbon fiber reinforced polymer (HM CFRP) materials for the retrofit of steel structures and bridges. The research work included selection of an appropriate adhesive for bonding HM CFRP materials to steel and the performance of Large-scale steel-concrete composite beams tested to examine the behavior of different strengthening schemes. The research findings demonstrate the effectiveness of the proposed HM CFRP strengthening system.
Nonlinear Behavior of Steel-Concrete Composite Beams Curved in Plane with CFRP Strips Bonding
This paper deals with the behavior of structural steel-concrete composite beams curved in plane. The analytical investigation included the use of three dimensional nonlinear finite elements to model the performance of the composite beams strengthened with CFRP strips by using (ANSYS 11.0) computer program. The numerical results showed very good agreement with the experimental results reach to 100% before the strengthening, while the increase in strength after the curved strengthened with CFRP strips 32% for the curve beam with L/R equal to 0.05 and 48% for the curve beam with L/R equal to 0.10 and 53% for the curve beam with L/R equal to 0.25.
