Abstract:
The paper presents an analytical study on FRP–strengthened RC sectionsunder combined bending and axial load. A secant approach is used that comparesquite well with the exact one. As a result, closed-form equations are developed fordesigning in a straightforward way the amount of FRP needed to flexurally strengthenunder–designed concrete columns.
