Nonlinear behavior of steel-concrete composite beams curved in plane with cfrp strips bonding

الملخص EN

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.
